Description

FIELD OF THE INVENTION

The invention relates to Hepatitis B surface antigen ("HBs antigen" or "HBsAG") particles which are composed of polypeptides prepared by recombinant DNA processes, DNA sequences coding for these polypeptides and cell lines for the expression of the same. The present invention relates especially to new particles having increased immunogenicity.

BACKGROUND OF THE INVENTION

Expression in Host Cells

Advances in vaccine production techniques have made it possible to synthesize polypeptides corresponding to the HBs antigen in bacteria, yeast and mammalian cells. Transcription of eukaryotic genes in bacteria and yeast, however, adversely affects the efficaciousness of these polypeptides as antigens due to several drawbacks concerning the glycosilation and secretion of the polypeptides and composition of the particle formed therefrom.

For example, in the case of the Hepatitis B virus, the polypeptide antigens produced in vivo are heavily glycosilated (Gerlich, 1984: J. Virol.: 52 (2), 396). In prokaryotes, glycosilation is not an essential process so that polypeptides produced by genetically engineered bacteria are either not glycosilated or are incompletely glycosilated. In either case, polypeptides corresponding to HBsAg, when expressed in bacteria, do not raise antibodies which will see HBsAg sufficiently well for an effective vaccine. Although yeast as a eukaryotic host is capable of more complete glycosilation, polypeptides corresponding to HbsAg expressed in yeast share the same deficiency as in the case of bacterial expression. (Murray et al., 1979: Nature, 282, 575; Valenzuela et al., 1982: Nature, 298, 347; Miyanohara et al., 1983: PNAS, 80, 1).

As a further example, in bacteria the eukaryotic structural gene of the HbsAg is in most cases not efficiently transcribed. Furthermore the structure and function of the eukaryotic HBsAg gene product may be dependent on the additional post-translational processes of the linkage of disulfide bonds which can not be accomplished by the bacterial host.

Still further, the expressed polypeptide is rarely secreted from the bacterial host cells. They must be lysed to harvest the expressed polypeptide. During the purification process bacterial wall components may contaminate the polypeptide and cause serious allergic reactions or lead to anaphylactic shock in patients.

Finally, eukaryotic promoters usually do not work in bacteria and must be substituted by a bacterial promoter which can result in modification of the polypeptide expressed, (Offensperger et al., 1985: PNAS, 82, 7540; Valenzuela et al., 1980: ICN-UCLA Symp, Mol. Cell. Biol., 18 57).

FORMATION AND SECRETION OF PARTICLES

The natural forms of Hepatitis B virus ("HBV") and HBV protein occur in three distinct morphologies:

the HBV-virion (Dane particle), which is thought to be the infectious material, the filaments, and the 20 or 22 nm particles (hereinafter "20 nm particle") which consist only of a protein envelope.

The most interesting form for an efficient vaccine is the 20 nm particle because 1) the coding sequences are entirely known, 2) it is completely uninfectious, and 3) it causes some useful immunogenicity in a human organism.

The three known components of HBV particles differ in their relative amounts of the protein composition. There are three monomers called the major protein with 226 amino acids, the middle protein with 281 amino acids, and the large protein with 389 or 400 amino acids, depending on the subtype ayw and adw, respectively. The large protein is encoded by the complete sequence of the pre-S.sub.1 -, pre-S.sub.2 - and S-regions, whereas the middle protein is derived from only the pre-S.sub.2 - and S-regions, and finally the major protein from only the S-region (Tiollais et al., 1985: Nature, 317, 489; Dubois et al., 1980: PNAS, 77, 4549; McAlzer et al., 1984: Nature, 307, 178).

The infectious virion of HBV (Dane particle) contains 40-80 times more of the high molecular monomers--the pre-S.sub.1 and pre-S.sub.2 peptides--compared to the 20 nm particle. It is now known that these pre-S polypeptides may be associated with some biological and clinical implications. The polyalbumin receptor on the pre-S polypeptides can bind polymerized albumins from humans and chimpanzees which are susceptible to HBV (Thung et al., 1983: Liver, 3, 290; Machida et al., 1984: Gastroenterology, 86, 910). This narrow host range and the known receptor for poly human serum albumin on human hepatocytes explain the hepatotropism of HBV: Dane particles are able to contact hepatocytes via poly human serum albumin taken up by hepatocytes from circulation. Based on this evidence the pre-S peptides should be helpful for an efficient vaccine against HBV because its antibody could be expected to block the significant site on Dane particles that are required for entering hepatocytes (Tiollais et al., 1985: Nature, 317, 489; Millich et al., 1985: Science, 228, 1195).

Literature data would also suggest a better protection against the infectious Dane-particle where the pre-S.sub.1 epitope is present in much higher ratio than on the envelope particles.

The vaccine obtained from natural sources (e.g., donor blood), which causes a limited immunogenic protection, contains (almost) none of the pre-S proteins; this is due to two different reasons. First, the purification process is focused on the noninfectious 20 nm particles. These contain at most 1% pre-S.sub.1 peptide compared to 15-20% in the Dane particle (Gerlich, 1984: J. Vir., 52 (2), 396; Tiollais et al., 1985: Nature, 317, 489; Gerlich, 1982: Virology, 123, 436). Second, the 20 nm particles are isolated from sera of anti-HBE positive carriers (Hevac B, HepaVac B) or are digested by proteases during the purification process. This proteolytic digestion has been shown to cut the pre-S-polypeptides leaving only the S monomer. As a result these vaccines contain none or very little pre-S polypeptides.

Therefore there is a demand for a vaccine in the form of HBs antigen particles which possess a high immunogenicity due to the composition of the particle, which undergo glycosilation in the cell and which are secreted continuously from the particle-producing cell.

Laub et al., J. Virol., Vol. 48, No. 1, pp. 271-280, 1983, disclose the construction of a vector starting from simian virus 40 into which the HBsAg including the 163 codon precursor sequence was incorporated. Laub et al. report that CV-1 cells transformed with said vector yield a better expression when the vector contains only the coding sequence for the S protein as compared to the above vector which comprises additionally also the 163 codon precursor sequence.

Also Takeda Chemical Ind., Japanese Patent Application No. J5-8194-897-A describes the expression of the entire pre-S and S peptides. Reference is also made to the expression of the adw subtype.

Feitilson et al., Virology, Vol. 130, pp. 75-90, 1983, have described the partial expression of polypeptides within the pre-S coding sequence, including species with 24000, 28000, 32000, 43000 and 50000 dalton.

Further, DE-OS 34 39 400 describes the expression of an immunogenic polypeptide sequence of Hepatitis B virus.

Said sequence represents a partial sequence of the pre-S.sub.1 polypeptide, comprises 108 or 119 codons and starts with the first starting codon of HBsAg, and terminates 281 codons in front of the stop codon.

EP-A-154 902 discloses a Hepatitis B vaccine which contains a peptide with an amino acid chain of at least six consecutive amino acids within the pre-S chain coding region of the envelope of Hepatitis B virus. This vaccine is free of an amino acid sequence corresponding to the naturally occurring envelope proteins of Hepatitis B virus.

Also Kent et al. have described in Pept. Chem., Vol 22, pp. 16770, 1984, that a chemically synthesized peptide comprising the N-terminal 26 amino acids of the pre-S.sub.2 region can serve as an antigen and may therefore be suitable as a synthetic vaccine.

OBJECTS OF THE INVENTION

None of the above discussed references consider the possibility that, by altering the composition of the monomers making up the 20 nm particles and approaching thereby the natural composition of the Dane particle, the antigenicity of the particle can be improved.

As discussed mentioned above, the immunogenicity of the peptide monomers of the virus envelope protein is very poor compared to assembled protein particles. The object of this invention is the development of protein particles which contain an amount of the pre-S polypeptide epitopes comparable to the natural composition of the surface structure of the infectious Dane particle.

It is a further object to utilize additional pre-S peptides containing important protective epitopes in the development of a better immune response, a longer protection and lower non-responder rate as compared to all the other products either already marketed or under development.

It is a further object to express HBsAg in mammalian cells. This requires overcoming known difficulties where expression of the desired peptide in a mammalian cell can result in:

different regulatory mechanisms for the three translational/(transcriptional) products promoter-promoter inhibition different strength of the start codons not all peptides expressed.

SUMMARY OF THE INVENTION

The term "HBV S peptide" as used herein refers to the peptide encoded by the entire S region of the HBV genome. The term "HVB pre-S.sub.2 peptide" as used herein refers to the peptide encoded by the entire pre-S.sub.2 and S regions of the HBV genome. The term "HBV pre-S.sub.1 peptide" as used herein refers to the polypeptide encoded by the entire pre-S.sub.1, pre-S.sub.2 and S regions of the HBV genome. The term "epitope" as used herein refers to a sequence of at least six consecutive amino acids encoded by the designated genome region (e.g., a "HBV pre-S.sub.2 epitope" refers to a sequence of at least six amino acids encoded by the pre-S.sub.2 region of the HBV genome). As used herein "antigenicity" means the ability to provoke an immune response (e.g., acting as a vaccine or an antigen), the ability to cause the production of antibodies (e.g. acting as an antigen) and/or the ability to interact with a cell surface receptor so as to enhance an immune response or production of antibodies (e.g., reacting with a T-cell surface receptor to enhance immune response).

The term "HBV" means any subtype of the virus, particularly adw, ayw, adr and ayr, described in the literature (P. Valenzuela, Nature Vol. 280, p. 815 (1979), Gerlich, EP-A-85 111 361, Neurath, EP-A-85 102 250). Examples of peptide sequences thereof, from which the epitopes of this invention can be derived are shown in FIGS. XVI to XX.

In accordance with the present invention, recombinant DNA molecules are disclosed which comprise a first DNA sequence and a second DNA sequence. The first DNA sequence encodes for expression of an amino acid sequence a portion of which displays the antigenicity of an epitope selected from the group consisting of an HBV pre-S.sub.1 epitope and an HBV pre-S.sub.2 epitope. The second DNA sequence encodes for expression of a peptide which upon secretion will form particles which are at least 10 nm in diameter. These particles are believed to be the smallest particles which will effectively form a good vaccine. Preferably the peptide which upon secretion will form particles which are at least 10 nm in diameter is either HBV S peptide, HBV core antigen, polio surface antigen, Hepatitis A surface antigen, Hepatitis A core antigen, HIV surface antigen and HIV core antigen. A substantial portion or all of the HBV S peptide is especially preferred as the peptide encoded by the second DNA sequence. In the recombinant DNA molecules encoding for the first and second DNA sequences must be (1) in the same reading frame, (2) encode for respective discrete regions of a single peptide, and (3) be operatively linked to an expression control sequence. Finally, these recombinant DNA molecules are free of DNA sequences encoding for the expression of the entire HBV pre-S.sub.1 peptide or HBV pre-S.sub.2 peptide.

Specific recombinant DNA molecules of the present invention are also disclosed wherein the first DNA sequence comprises a nucleotide sequence corresponding to the nucleotide sequence of (1) the HBV pre-S.sub.1 and pre-S.sub.2 regions from which the pre-S.sub.2 start codon ATG has been deleted, (2) the HBV pre-S.sub.1 and pre-S.sub.2 regions and wherein the sequences flanking the pre-S.sub.1 ATG have been changed from the natural sequence, (3) the HBV pre-S.sub.1 and pre-S.sub.2 regions and wherein the sequences flanking the pre-S.sub.2 ATG have been changed from the natural sequence, (4) the HBV pre-S.sub.1 and pre-S.sub.2 regions and wherein the 5' terminus of the pre-S.sub.1 region has been deleted, (5) the HBV pre-S.sub.1 and pre-S.sub.2 regions and wherein the 5' terminus of the pre-S.sub.2 region has been deleted, (6) the HBV pre-S.sub.1 region and wherein the 3' terminus of the pre-S.sub.1 region has been deleted, (7) the HBV pre-S.sub.2 region has been deleted, (8) the HBV pre-S.sub.1 and pre-S.sub.2 regions from which the pre-S.sub.2 ATG has been deleted and the second DNA sequence comprises a sequence corresponding to the nucleotide sequence of the HBV S region from which the S ATG has been deleted, and/or (a) an oligonucleotide described in Table I.

Host cells transfected with the recombinant DNA molecules of the present invention are also disclosed. As used herein, "transfected" or "transfection" refer to the addition of exogenous DNA to a host cell whether by transfection, transformation or other means. Host cells include any unicellular organism capable of transcribing and translating recombinant DNA molecules including without limitation mammalian cells, bacteria and yeast. Host cells of the present invention may also be cotransfected with a second recombinant DNA molecule comprising a DNA sequence encoding for expression of an amino acid sequence corresponding to a substantial portion or all of the amino acid sequence of the HBV S peptide.

Peptides are also disclosed comprising a first discrete region and a second discrete region. The first region displays the antigenicity of an epitope of an HBV pre-S.sub.1 epitope or an HBV pre-S.sub.2 epitope. The second region correspond to a substantial portion of a peptide which upon secretion will form particles which are at least 10 nm in diameter. Preferably the peptide which upon secretion will form particles which are at least 10 nm in diameter is either HBV S peptide, HBV core antigen, polio surface antigen, Hepatitis A surface antigen, Hepatitis A core antigen, HIV surface antigen and HIV core antigen. A substantial portion or all of the HBV S peptide is especially preferred. Preferably, the first region is located closer to the N-terminus of the peptide than the second region.

Immunogenic particles are also disclosed which comprise a plurality of first peptide monomers. Each of said first peptide monomers comprises a first discrete region and a second discrete region which can be the same as the first and second discrete regions of the peptides described above. Immunogenic particles are also disclosed which further comprise a plurality of second peptide monomers and wherein the first and second peptide monomers are bound together by interactive forces between the monomers. Each of said second peptide monomers comprising an amino acid sequence corresponding to a substantial portion of or all of the amino acid sequence of the HBV S peptide.

Immunogenic particles are also disclosed which contain substantially more than one percent, preferably more than five percent, of the pre-S.sub.1 epitope. As used herein, a particle "contains one percent" of a designated epitope if peptide monomers having the designated epitope constitute one percent of all protein in the particle. Immunogenic particles which contain substantially more than ten percent, preferably more than fifteen percent, of the pre-S.sub.2 epitope are also disclosed.

The process may further comprise exposing the host cells to a second preparation of DNA comprising a DNA molecule encoding for a peptide including the amino acid sequence of the HBV S peptide and allowing under suitable conditions the host cells to take up DNA from the second preparation of DNA. The exposure and uptake of the second preparation of DNA can be done before or after exposure to and uptake of the first DNA preparation. Alternatively, the first DNA preparation can also include a DNA molecule encoding for a peptide including the amino acid sequence of the HBV S peptide.

A method for producing a peptide is also disclosed which comprises preparing an above-described recombinant DNA molecule, transfecting a host cell with the recombinant DNA molecule, culturing the host cell under conditions allowing expression and secretion of protein by the host cell, and collecting the peptide produced as a result of expression of DNA sequences within the recombinant DNA molecule. The peptide produced by such method can contain less than the entire amino acid encoded by the coding region of the recombinant DNA molecule.

The cotransfection can occur before, after or simultaneous with the transfection of the above-described recombinant DNA molecule. Presence of peptides encoded by the cotransfected DNA molecule are necessary to obtain more than trace amounts of particles secreted from the host cell.

Other adapter sequences may be used to combine desired oligonucleotides from Table I with the XbaI-BglII fragment, other restriction fragments, oligonucleotides and other construct components. The necessary sequences of such other adapter sequences will be readily apparent to those skilled in the art from consideration of tables of restriction sites [e.g., that found at pages 121-128 of Methods in Enzymology, volume 152, "Guide to Molecular Cloning Techniques," ed. Berger and Kimmel (Academic Press 1987) which is incorporated herein in its entirety by reference] and the sequences of the various nucleotides to be combined. Adapter sequences can also be used to introduce additional restriction sites into constructs of the present invention. It should be noted that adapter sequences must be selected or designed so that the proper reading frame is maintained throughout the HBV sequence.

Preferred gene constructs which were used to transfect host cells were prepared by recombinant DNA techniques in accordance with the present invention. Preferred embodiments of constructs with an enhanced expression rate are shown in FIGS. I-VIII and are schematically represented by the following:

pU2-structural gene pU2-structural gene-dhfr pU2-structural gene-dhfr-MT-neo pU2-structural gene-dhfr-MT-egpt pMT-structural gene-dhfr pMT-structural gene-dhfr-MT-neo pMT-structural gene-dhfr-MT-egpt pH2K-structural gene-dhfr pH2K-structural gene-MT-neo pH2K-structural gene-MT-egpt pH2K-structural gene-dhfr-MT-neo pH2K-structural gene-dhfr-MT-egpt

Each of the constructs shown in FIGS. 1-VIII contain, in addition to a HBV sequence, a neomycin selection marker with the MT promoter, an ampicillin selection marker, a dhfr selection/amplification gene and a promoter for the HBV sequence. The promoter for the HBV sequence is preferably the U2 promoter, the MT promoter or the H2K promoter. Isolation of fragments containing the various promoters, the selection markers and amplification gene is described below. The HBV sequences in the constructs of FIGS. I-VIII are schematically represented by a rectangular bar in each figure which indicates the oligonucleotides and/or adapter sequences from Tables I and II which are combined with the XbaI-BglII fragment. Shaded areas within the bar indicate generally regions of the entire pre-S.sub.1 -pre-S.sub.2 -S region which are not found in the specific construct. Oligonucleotides from Table I which can be used to construct each type of HBV sequence are indicated in the figures.

FIG. 10 depicts two additional constructs for expression of peptides including sequence from the pre-S2 region under the control of the MT promoter.

Constructs have also been made which include the entire BGlII-BglII fragment from the HBV genome under the control of the US promoter. These constructs have produced peptides which include a deletion in the S region as indicated by Western blot analysis.

The above-cited promoters are specifically preferable when their use is coupled with a modulation method using the dhfr gene and methotrexate to enhance the expression. This is achieved when in addition to the selection marker the dhfr minigene is also introduced into the plasmid sequence. It is essential that the dhfr gene is located on the same plasmid together with the structural gene to be expressed. An enhancement of the expression rate of the structural gene can then be obtained by adding methotrexate in the micromolar concentration range. Thereby a manyfold enhancement of the expression rate is achieved.

Suitable cells are e.g. VERO cells (monkey kidney cell line), 3T3-cells (murine fibroblast line), C127-cells (murine fibroblast line), L-cells and CHO-cells (Chinese hamster cells, which are either positive or negative in dehydrofolate reductase).

As a stop signal it is preferred to use a stop signal from a eukaryotic cell. Preferably the stop signal of the caseine DNA-sequence is used. As used throughout the following examples, "HBV protein" refers generically to any protein produced in accordance with the present invention which corresponds to HBsAg sequences.

EXAMPLE 1

Particle Purification Procedures 1. Fractionated precipitation with polyethylene glycol (PEG)

The supernatant of HBV protein producing cultures was collected and split into portions of 2,400 ml. To each portion 144 g of PEG 6000 (Serva) were added and dissolved by stirring at room temperature for 20 minutes and was stirred for another 6 hours at 4.degree. C. The precipitate was separated by centrifugation in 500 ml bottles in a GS 3 rotor at 9,000 rpm (15,000.times.g) for 30 minutes at 10 C. The supernatant was collected and 144 g of PEG 6000 were added and dissolved as described above. The solution was stirred at 4 C. for 3 hours. The precipitate from this solution was harvested as described above except that centrifugation was continued for 60 minutes.

2. Gel Chromatography

The material obtained after PEG precipitation was redissolved in 20 ml PBS and submitted to gel chromatography on A-5m (BioRad). Column dimensions were 25.times.1000 mm and 480 ml bed volume. In a typical fractionation run 1,000 ug of PEG precipitated HBV protein in 10 to 15 ml was loaded and eluted with PBS at a speed of 6 drops/min (18 ml/h) 3 ml fractions were collected. HBV protein eluted with the first peak. Collected fractions were submitted to a CsCl gradient.

3. Sedimentation in CsCl Gradient

About 30 fractions covering the first peak in column chromatography on A-5m and containing prepurified HBV protein were collected to approximately 100 ml. This solution was adjusted to a density of 1.30 g/cc with CsCl and subsequently transferred to a nitrocellulose tube fitting into a SW 27/28 rotor (Beckman). A gradient was set by underlaying 4 ml of a CsCl solution of 1.35 g/cc and by overlaying 4 ml of 1.25 g/cc followed by 4 ml of 1.20 g/cc density. This gradient had been run at 28,000 rpm for 50 hours at 10 C. Thereafter the gradient was fractionated and purified HBV protein floating in the 1.20 g/cc density layer was collected. The solution was desalted by three cycles of dialysis in bags against water.

Quantitative Determination of HBV protein 1. with Radioimmunoassay

In the AUSRIA II-125 "sandwich" radioimmunoassay (commercially available from Abbot), beads coated with guinea pig antibody to Hepatitis B Surface Antigen (Anti-HBs) were incubated with serum or plasma or purified protein and appropriate controls. Any HBsAg present was bound to the solid phase antibody. After aspiration of the unbound material and washing of the bead, human 125T-Anti-HBs was allowed to react with the antibody-antigen complex on the bead. The beads were then washed to remove unbound .sup.125 I-Anti-HBs.

In the Enzygnost HBsAg micro "sandwich" assay (commercially available from Behring), wells were coated with anti-HBs. Serum plasma or purified protein and appropriate controls were added to the wells and incubated. After washing, peroxidase-labelled antibodies to HBsAg were reacted with the remaining antigenic determinants. The unbound enzyme-linked antibodies are removed by washing and the enzyme activity on the solid phase is determined. The enzymatically catalyzed reaction of hydrogen peroxide and chromogen was stopped by adding diluted sulfuric acid. The colour intensity was proportional to the HBsAg concentration of the sample and was obtained by photometric comparison of the colour intensity of the unknown samples with the colour intensities of the accompanying negative and positive control sera.

EXAMPLE 6

Transfection of Mammalian Cells with Constructs of the Present Invention.

In order to achieve secretion of substantial amounts of the HBV peptides encoded by constructs of the present invention, mammalian cells must be transfected with both the construct of the present invention and a construct which will express entire S protein. The cotransfection was performed in two steps (i.e., a separate transfection for each construct) or in a single step (i.e., one transfection using preparation of both constructs). Cotransfection was confirmed either by use of different selection markers on the two constructs or by detection of secretion of expression products of both constructs by immunoassay.

Alternatively, a sequence encoding the HBV peptide sequence of the present invention and a separate sequence encoding the entire S protein could be combined in a single construct.

General Procedures

General procedures useful in practicing the present invention may be found in (1) Methods of Enzymology, volume 152, "Guide to Molecular Cloning Techniques," ed. Berger and Kimmel (Academic Press 1987), and (2) Maniatis et al., "Molecular Cloning: A Laboratory Manual," (Cold Spring Harber Laboratory 1982), both of which are incorporated herein in their entirety by reference. Specific techniques employed are described below.

1) Digestion with Endonucleases and Isolation of Fragments

The restriction endonucleases used were:

BglII, BamHI, HindIII, EcoRI, XbaI, MstII, XhoI, PflMI, commercially available from Gibco/BRL with their respective restriction buffers (10x).

Unless otherwire indicated, restriction digests were performed and fragments were isolated as follows. Reactions typically contained 1-5 ug DNA.

distilled water was added to the DNA in an eppendorf tube to a final volume of 8 ul 1 ul of the appropriate 10x digestion buffer was added 1 ul (containing 5-10 U) restriction enzyme was added and mixed carefully the reaction tube was incubated for 1 hour at 37.degree. C. digestion was stopped by adding 0.5 M EDTA (pH 8.0) to a final concentration of 10 mM if the DNA was analysed directly on a gel, 1 ul of gel-loading dye III (Maniatis) was added, mixed and the sample was loaded into the slots of a 0.8% agarose gel.

The agarose gel normally contains 0.8% agarose 1 x running buffer (BE, Maniatis). Where a fragment (about 100-1000 bp) was isolated from an agarose gel the agarose was increased to 1.2 to 1.4%.

2) Competent Bacterial Cells

From a dense overnight culture, 1 ml of the bacterial cell suspension was added to 100 ml fresh growth medium (L-broth). The cells were grown at 37.degree. C. to a density of OD.sub.600 =0.7 which was reachad within 2 hours with vigorous shaking in a 500 ml Erlenmeyer flask. Growth was atopped by chilling the culture on ice for 10 minutes. From this culture, 3 ml were taken for harvesting the exponential bacterial cells at 3,000 rpm for 5 minutes. The cells were resuspended in 1.5 ml of 50 mM CaCl.sub.2 in 10 mM Tris, pH 8.0, and incubated on ice for another 15 minutes. The cells were harvested once more by centrifugation at 3,000 rpm for 5 minutes and resuspended in 200 ul of 50 mM CaCl.sub.2 in 10 mM Tris, pH 8.0, and used directly.

3) Transformation of Competent Bacterial Cells

The DNA to be transformed was suspended in 10 mM Tris, pH 7.5, 1 mM EDT 70 ul and added to the 200 ul bacterial cell suspension for DNA take-up. The mixture was incubated on ice for 30 minutes and then 1 ml L-broth was added. The mixture was incubated at 42.degree. C. for 2 minutes and at 37.degree. C. for 40 minutes.

After the incubation, the cells were spread on agar plates containing 50 ug ampicillin/ml agar at volumes of 50-300 ul cell suspension per plate. The agar plates were incubated at 37.degree. C. overnight. After this incubation period, single isolated bacterial colonies were formed.

4) Plasmid DNA Isolation

1 liter of plasmid-bearing cells was grown to 0.5 OD.sub.600 in L-broth and amplified for 20 hours with 200 ug/ml chloramphenicol. The culture was then centrifuged at 4,000 rpm for 20 minutes in JA-10 rotor, 4.degree. C. The pellet was resuspended in 18 ml cold 25% sucrose, 50 mM Tris, pH 8.0, transferred to a 250 ml Erlenmeyer flask and kept on ice. 6 ml 5 mg/ml lysozyme in 250 mM Tris, pH 8.0 was added and the mixture was left to stand 10-15 minutes. 6 ml 250 mM EDTA, pH 8.0, was added, mixed gently and incubated for 15 minutes on ice. 30 ml detergent (0.01% Triton X-100; 60 mM EDTA, pH 8.0; 50 mM Tris, pH 8.0) was added and the mixture was incubated for 30 minutes on ice. After incubation, the mixture was centrifuged at 25,000 rpm 90 minutes in SW28 rotor, 4.degree. C.

Pronase was added to supernatant fluid to 250 ug/ml and incubated 30 minutes, 37.degree. C. The solution was extracted with phenol once with 1/2 volume phenol equilibrated with 10 mM Tris, pH 8.0, 1 mM EDTA. The aqueous layer was removed. Sodium acetate was then added to a final concentration of 300 mM, followed by the addition of 3 volumes cold 100% ethanol and thorough mixing. The mixture was stored at -20.degree. C. overnight.

The mixture was thawed and centrifuged. The pellet was resuspended in 6 ml 10 mM Tris, 10 mM EDTA, pH 8.0. 9.4 g CsCl and 0.65 ml of 6 mg/ml ethidium bromide were added and the volume was brought up to 10 ml with sterile double-distilled water. The 10 ml alignots were put into Beckman heat-sealable gradient tubes and centrifuged, 50,000 rpm, 48 hours in Ti70.1 Beckman rotor.

Plasmid bands were visualized with UV and removed with syringe and 18 gauge needle by piercing the side of the tube. Ethidium bromide was removed from the plasmid fractions by 3 successive extractions with equal volumes of isobutanol. Fractions were then (1) dialyzed against one 2-liter lot of 10 mM Tris, pH 7.4, 1 mM EDTA, pH 7.5, 5 mM NaCl for 2 hours or more at 4.degree. C.; and (2) phenol extracted once with 1/3 volume phenol equilibrated as above. Sodium acetate was then added to a final concentration of 300 mM, followed by addition of two volumes of 100% ethanol. Precipitate formed at -20.degree. C. overnight, or at -70.degree. C. for 30 minutes.

5) Mini-Plasmid Preparation

1 ml of an overnight bacteria culture was put into an eppendorf tube and centrifugated for 20 minutes. The supernatant was removed. 100 ul of 50 mM glucose, 25 mM Tris (pH 8.0), 10 mM EDTA (pH 8.0) was added to the pellet, mixed by vortex and incubated for 5 minutes at room temperature. 200 ul of 0.2 N NaOH, 1% SDS was added, mixed by vortex and incubated for 5 minutes on ice. 150 ul 3 M Sodium acetate (pH 4.8) was added, mixed by vortex and incubated for 5 minutes on ice. After centrifugation for 5 minutes at 13,000 rpm the supernatant was decanted into a fresh eppendorf tube. 3 volumes of 100% ethanol were supplemented, mixed well and incubated for 30 minutes at -80.degree. C., then centrifuged for 10 minutes at 13,000 rpm. The ethanol was removed, the pellet washed with 70% ethanol, lyophilized and dissolved in 20 ul distilled water. 5 ul of this plasmid DNA solution were used directly for restriction analysis.

6) Nick Translation

Nick translation was performed according to Rigby et al., J. Mol. Biol., Vol. 113, pp. 237-251, 1977, which is incorporated herein by reference. The reaction mixture for .sup.32 P-labeling of DNA contained 0.5 ug of a HBV fragment, in a total volume of 30 ul with 50 mM Tris, pH 7.8, 5 mM MgCl.sub.2, 10 mM mercaptoethanol, 0.1 mM dATP, 0.1 mM dGTP, 0.1 mM dTTP, 50 uCi .sup.32 P-dCTP, 10 unites DNA polymerase I, 3 ul of a 2.times.10.sup.-5 fold dilution of 1 mg/ml DNase I and is incubated for 90 minutes at 15.degree. C., yielding 3.times.10.sup.6 to 12.times.10.sup.6 total cpm, i.e. 1.times.10.sup.7 to 5.times.10.sup.7 cpm/ug DNA.

7) Southern Blot Analysis

To characterize the organization within the host cell genome of the vectors of this invention, chromosomal DNA from cell lines producing particles of this invention were isolated and digested with the appropriate restriction enzyme(s) and analysed by the method of Southern (J. Mol. Biol., Vol. 98, pp. 503-517, 1975), which is incorporated herein by reference, using a .sup.32 P-labeled DNA probe. Follwing digestion of the chromosomal DNA (20 ug) with the restriction enzyme BglII, the resulting fragments were separated by 0.7% agarose gel electrophoresis. Thereafter, the DNA was denatured by exposing to 366 nm UV light for 10 minutes and by incubation in a solution of 0.5 M NaOH and 1 M NaCl for 45 minutes. The gels were neutralized by incubation in 0.5 M Tris, 1.5 M NaCl, pH 7.5 for 60 minutes. The DNA was transferred to a nitrocellulose filter by soaking in 3 M NaCl, 0.3 M Sodiumcitrate (20 x SSC) for 20 hours through the gel by covering the top of the nitrocellulose filter with a staple of dry paper towels. The nitrocellulose filter was kept for 2 hours in a vacuum oven at 80 C. A radioactive DNA probe from the BglII fragment of the pHBV (2.3 kb) was prepared by nick translation.

For hybridization with the DNA probe, the nitrocellulose filter was sealed in a plastic bag containing 10 ml of prehybridization mixture: 50% formamide, 5 x SSC, 50 mM Sodiumphosphate, pH 7.0, 5 x Denhardt's solution, 250 ug/ml denatured salmon sperm DNA. The filter was incubated in this mixtue for 4 hours at 45.degree. C., after which the pre-hybridization mixture was replaced by the hybridization mixture: 50% formamide, 5 x SSC, 20 mM Sodiumphosphate, pH 7.0, 1 x Denhardt's solution, 100 ug/ml denatured salmon sperm DNA, 5.times.10.sup.5 cmp/ml .sup.32 P-probe. The filter, after incubating in the hybridization mix for 18 hours at 45.degree. C., was washed three times, 5 minutes each, in 0.1 x SSC, 0.1% SDS at 50.degree. C. The filter was dried at 60.degree. C. for 10 minutes and exposed to two X-ray films (XAR-5, KODAK) between two intensifying screens and kept at -80.degree. C. The first X-ray film is developed after 3 days' exposure; the second film after 7 days' exposure.

8) Preparation of Mammalian Cells and DNA Precipitate for Transfection

The recipient cells (C127 or CHO-cells available from ATCC) were seeded in normal growth medium (DMEM+10% Fetal Calf Serum, Glycose and Glutamin) into petri-dishes (1-2.times.10.sup.6 cells per dish, .PHI. 10 cm) at day 1. The next day the medium was removed (4 hours before the DNA precipitate was added onto the cells), and the cells were washed twice with 1 x PBS. Then 8 ml DMEM without FCS were added. 4 hours later the DNA precipitate (prepared as described below) was added to the cells. Again after 4 hours the medium was removed, 3 ml of Glycerol-Mix (50 ml 2 x TBS buffer, 30 ml glycerol, 120 ml distilled water) were added. The Glycerol-Mix was immediately removed after an incubation at 37.degree. C. for 3 minutes and the cells were washed with 1 x PBS. The cells were cultivated overnight with 8 ml of DMEM with 10% FCS.

After 48 hours, the cells were recovered from the dish by treating with Trypsin-EDTA-Solution (0.025% Trypsin+1 mM EDTA). Afterwards, to remove the Trypsin-EDTA the cells were washed with 1 x PBS, suspended in DMEM with 10% FCS and distributed into 24 costar-well-plates (cells from one dish into four 24-well-plates). When the cells had grown well, selection medium was added (concentration 0.5-1 mg/ml of neomycin, or xanthine: 250 .mu.g/ml, hypoxanthine: 15 .mu.g/ml (or adenine: 25 .mu.g/ml), thymidine: 10 .mu.g/ml, aminopterine 2 .mu.g/ml mycophenolic acid: 25 .mu.g/ml for eco-gpt, for example). The medium was changed every week. The first growing cell colonies were seen after 2 weeks.

To 10 ug of plasmid DNA and 20 ug of carrier-DNA (salmon-sperm DNA, calf-thymus DNA) TE-buffer (10 mM Trix-HCl, 1 mM EDTA, pH 7.05) was added to a final volume of 440 ul and mixed together with 60 ul 2 M CaCl.sub.2. Then the same amount of 2x TBS (Hepes 50 mM, NaCl 280 mM, Na.sub.2 HPO.sub.4 1.5 mM, pH 7.05) was added and mixed well. The precipitation solution was incubated for 30 minutes at 37.degree. C. and added directly to the cells which should be transfected.

EXAMPLE 9

F) Preparation of the Adjuvant of Purified Particles

To the desired concentration of antigen particles suspended in sterile saline, 1:10,000 volume Thimerosol, 1/10 volume of filter-sterilized 0.2 M Al K(SO4).sub.2 :12 H.sub.2 O were added. The pH was adjusted to 5.0 with sterile 1 N NaOH and the suspension was stirred at room temperature for 3 hours. The alum-precipitated antigen was recovered by centrifugation for 10 minutes at 2,000 rpm, resuspended in sterile normal saline containing 1:10,000 Thimerosol and aliquoted under sterile conditions.
