Pool and superpool matrix coding and decoding designs and methods

Abstract

This application pertains to construction of pooled biological material such as DNA, RNA, proteins and the like that are able to be screened by a wide variety of methods such as PCR (Polymerase Chain Reaction), DNA/DNA hybridization, DNA/RNA hybridization, RNA/RNA hybridization, single strand DNA probing, protein/protein hybridization and a wide variety of additional methods. Our new method for construction of pools and superpools for screening differs in that the complete set is systematically divided into a variety of smaller subsets which are then re-pooled to make the final screening pools. This pooled material can be from individual samples or a population of samples. In order to reduce the analysis time, materials and expense, the pooling of high resolution small pools in a matrix allows for a lower number of user experiments to have higher resolution (as if the researcher had analyzed the complete set of small pools).

BACKGROUND OF THE INVENTION

[0021] This application pertains to construction of pooled biological material such as DNA, RNA, proteins and the like that are able to be screened by a wide variety of methods such as PCR (Polymerase Chain Reaction), DNA/DNA hybridization, DNA/RNA hybridization, RNA/RNA hybridization, single strand DNA probing, protein/protein hybridization and a wide variety of additional methods. References describing many of these methods include “Ausubel et.al. Short Protocols in Molecular Biology, Wiley and Sons, New York” and “Sambrook et.al, Molecular Cloning, A Laboratory Manual, Cold Spring Harbor Press, New York” as well as numerous others and are hereby included by reference. Also included by reference are U.S. Pat. No. 5,780,222 (Method of PCR Testing of Pooled Blood Samples) and its references cited. Also included are U.S. Pat. Nos. 6,126,074 and 6,477,669 and their references including the references pertaining to Veterbi, Reed-Solomon and other Error Correction and Data Compression Coding schemes. This pooling method will allow the incorporation of ‘loss-less information compression and error correction’ or other ‘current art’ error correction strategies to improve the robustness of identification with significantly reduced numbers of samples to be processed by the end user. By having the samples pooled again after collection, it is possible to drastically reduce the manipulations required by the end user while still keeping very fine detail in the identification of the individual samples or populations that were originally pooled. These error-correction methods are well known in the computer data transmission field, but have not been used in the pooling of biological or chemical samples. The use of these methods will allow a large reduction in the number of experiments required to identify the specific biological sample or population containing a region of interest.

[0022] The current state of the art in pooling of biological materials such as Bacterial Artificial Chromosome (BAC) genomic DNA libraries (and other biological or chemical libraries like cDNA libraries, protein libraries, RNA libraries, DNA libraries cellular metabolic libraries and chemical libraries) for screening consist of the collection of all of the indexed microtiter plates containing the BAC library and then forming these plates into a large cube. These indexed plates are generally 96, 384, 864 well or sometimes even 1536 well microtiter plates. This large cube is then transected by a number of different planes (usually 4 to 8) which produce a large number of pools from each plane. This collection of all of the pools from all of the planes are then screened to identify the clones of interest. This scheme is the current state-of-the-art and can identify multiple clone hits with some degree of reliability to identify multiple targets (i.e. BAC clones) at a specific coordinate. According to Klein et al., their scheme with 6 planes in a collection of 24,576 BAC's could detect between 2 and 6 BAC's and over 90% could be reliably assigned to a specific coordinate with 184 screening pools (that is 184 user experiments are required).

BREIF SUMMARY OF THE INVENTION

[0023] Our new method differs in that the complete set is systematically divided into smaller subsets which are then re-pooled to make the final screening pools. This pooled material can be from individual samples or a population of samples. In order to reduce the analysis time, materials and expense, the pooling of high resolution small pools in a matrix allows for a lower number of user experiments to have higher resolution (as if the researcher had analyzed the complete set of small pools). One of the preferred embodiments describes a two step method that first screens for which superpool. Then that specific superpool's pools have been re-pooled into matrix pools (which are 36 matrix pools instead of 76 pools). The matrix pools are screened in this method also gives the added advantage of having two or more positive signals needed for identification (as shown in our provisional application). This reduces the current state-of-the-art problems associated with a false positive and/or false negative experimental result when only one signal is obtained for identification.

[0024] The matrix pooling can be just in one superpool (as we have shown in the detailed description of our matrix manual in our provisional application). Alternately, it can be a matrix of a variety of different superpools and/or across a variety of different types of pools to allow the screening of the complete library with just one round of experiments. To do this, each small pool would be combined with any number (generally between six and many thousands depending on the sensitivity/robustness of the users experimental screening strategy) of final collection pools (which are re-pooled intermediate pools). For this example we'll use the range of 6 and 20 collection pools (fully compatible with a PCR based screening technology). Then with the total number of pools of between 40 and 180, and more preferably between 80 and 96, the complete library could be screened with high confidence and the ability to resolve multiple samples in the library containing an identical region of interest. If the library had a large redundancy of signal, the total number of pools could be increased to maintain accurate resolving power of the matrix methodology. The incorporation of positive controls in a matrix patterncan be used to for quality assurance and for assisting in deconvolution if desired.

DETAILED DESCRIPTION OF THE INVENTION

[0026] EXAMPLE 1

[0027] Detailed Description of Pools & Superpools:

[0028] This description is based on 384 well index plates, but it could be used with other plate formats as well with appropriate considerations. It is also based on a BAC genomic DNA library comprised of individual BAC clones, but it could be used with a large variety of biological sample collections or chemical sample collections. The system consists of a collection of multiple Superpools that are screened during First Round PCR, to determine which set of Matrix Pools to screen during Second Round PCR. The total number of Superpools is determined by the total number of clones in the BAC library. Each Superpool has it's own 96-well plate of corresponding Matrix Pools.

[0029] Superpools: Each superpool consists of twelve consecutive 384-well plates from a BAC library. DNA is prepared by growing EACH BAC CLONE separately (to avoid growth competition between BAC clones) then combining the 4,608 cultures into one large-scale BAC prep. The Superpool of BAC DNA is then aliquoted onto a 96-well plate. Superpool SP-1 has all the BAC clones in the first twelve plates of the BAC library (Plate 001 to Plate 012).

[0030] Superpool SP-2 has all the BAC clones in the second twelve plates of the BAC library (Plate 013 to Plate 024). This naming continues for the entire library.

[0031] Matrix Pools: For each superpool there is one set Matrix Pools (this set of 36 Matrix Pools are aliquoted onto a Matrix Pool Plate. The Matrix Pools of Superpool #1 are named:

[0032] Matrix Plate Pools 1MPP-A1 through 1MPP-H1 for the 8 wells that contain the matrix of plates 1-12 in Superpool one. Each Matrix Plate Pool contains 1,152 clones. Table 1 indicates the clones in each well. The same process is repeated for as many superpools as are needed for the complete library.

[0034] Matrix Column Pools 1MPP-A3 through 1MPP-B4 for the 10 wells that contain the matrix of columns 1-24 in Superpool #1. See table 3 for the exact composition of each well in the Matrix Column Pools. The Matrix Column Pools in wells A3 through D3 have 1,152 clones (6 different columns X 192 column wells/plate=1,152 clones per Matrix Column Pool).

[0035] Matrix Diagonal Pools 1MDP-G4 through 1MDP-H5 for the 10 wells that contain the matrix of diagonals 1-24 in Superpool #1. See table 4 for the exact composition of each pool in the Diagonal Pools. The diagonal pools are a collection of clones from all twelve plates in one superpool that has been transected by a plane that goes diagonal in an XY plane and diagonal in a XZ plane through the 12 plates. The diagonals are named by the number of the column that the clone from row A on plate 1 of the specific diagonal. Table 5 shows the exact composition of the Matrix Diagonal Pools. In wells G4 through B5 have 1,152 clones (6 different diagonals X 12 plates/diagonal X 16 column wells/plate=1,152 clones per Matrix Diagonal Pool). The Matrix Diagonal Pools in wells C5 through H5 contain 768 clones (4 different diagonals X 12 plates/diagonal X 16 column wells/plate=768 clones per Matrix Row Pool).

[0036] It is clear that this table is but just an example of a diagonal scheme that is non-redundant with other pools. This table is not limited to one specific diagonal, since there are additional diagonal strategies that can also included as obvious expansions on this diagonal strategy.

[0037] After screening the matrix pools by one of many possible methods, the identity of a specific positive clone from the library can be determined. The specific identification can be determined by a number of ways. If the pool design and matrix design are written or available in electronic form, the unique clone can be identified by a visual or electronic search. There can also be algorithms written based on the pool and matrix designs that can identify the unique clone.

[0038] The second example describes a method to form a matrix of a variety of different superpools and/or across a variety of different types of pools to allow the screening of the complete library with just one round of experiments. To do this, each small pool would be added to between 6 and 20 of the collection of re-pooled intermediate or final pools. Then with the total number of pools of between 40 and 180, and more preferably between 80 and 94, the complete library could be screened with high confidence and the ability to resolve multiple hits. If the library had a large redundancy of signal, the total number of pools could be increased to maintain accurate resolving power of the matrix solution. Note: 94 experiments is the preferred number, because current screening technologies are performed on a 96-well index plate format (94 experiments will allow room for a positive control and negative control).

[0039] In the second example we will teach an additional method that allows the complete library to be screened in one step while still maintaining the resolution of the superpool individual pools formed in Example 1.

EXAMPLE 2

[0040] This example further illustrates and teaches the advantages and possibilities of the current invention. This example is also based on 384 well index plates, but it could be used with other plate formats as well with appropriate considerations. It is also based on a BAC genomic DNA library comprised of individual BAC clones, but it could be used with a large variety of biological collections. The superpools will be composed of eight 384 well plates per superpool and with 10 superpools combined into one large set of matrix pools. Therefore there will be 80 plates (30,720 individual BAC clones in the library) in this one matrix screening that can be tested with a limited number of tests while still maintaining good resolution to an individual clone or may possibly requires screening a few clones during the clone confirmation test directly on the clone(s) of interest. This scheme also allows a single set of experiments (instead of two sets of experiments as described in Example 1).

[0041] In this scheme, the individual superpools are numbered so that each individual ⅓ plate, row, column and diagonal pool has a unique number. Since there are 88 pools per superpool and ten superpools in this example, there are a total of 880 individual pools that will be combines into one large set of matrix pools. Depending on the number of redundant clones in the BAC library (a function of the genome size and the insert size of the BAC clones), the idealized degree of redundancy can dramatically improve the ability to identify multiple positive clones in one screening and thus minimize ambiguous results (when the user is analyzing data from the screening experiments).

[0042] The first ⅓ plate pools are formed by collecting all of the clones in plate 1 from columns 1-8. Then the second ⅓ plate pool is all of the clones from columns 9-16 of plate one. This continues on until the 24th ⅓ plate pool is from columns 17-24 of plate 8. The twenty-four ⅓ plate pools from superpool two would be considered being in pools 89-112 and so on until the tenth superpool where the ⅓ plate pools would be in pools 793-816.

[0043] The row pools would be built the same way as Example 1 but since there are only 8 plates in each superpool, each pool would have 192 clones. All of the clones in row A of the eight plates would be pooled together and these clones would be considered pool number 25. This would continue on in a similar fashion so all of the clones in row B of all eight plates of the superpool would belong to pool 26 (and so on) until finally, the pool of all of the clones in row P of the first eight plates would belong to pool number 40. Similarly, the row pools from the second superpool will be in pools numbered 113-128. This would continue in a similar fashion until all of the superpool individual clones belong to row pools and each are assigned unique numbers.

[0044] The column pools would be formed the same way as in Example 1 but since there are only 8 plates in each superpool, each pool would have 128 clones. All of the clones in column 1 of the eight plates would be pooled together and would belong to pool number 41. This would continue on in a similar fashion until all of the clones in column 2 of all eight plates of the superpool would belong to pool 42 (and so on). Until finally, the pool of all of the clones in column 24 of the first eight plates belong to pool number 64. Similarly, the column pools from the second superpool will be in pools numbered 129-152. This would continue in a similar fashion until all of the superpools belong to column pools and each are assigned unique numbers.

[0045] The diagonal pools would be formed the same way as in Example 1 but since there are only 8 plates in each superpool, each pool would have 128 clones. See table 6 for the 8 plate superpool diagonal composition. All of the clones in diagonal 1 of the eight plates would be pooled together and would belong to pool number 65. This would continue on in a similar fashion until all of the clones in diagonal 2 of all eight plates of the superpool would belong to pool 66 (and so on). Until finally, the pool of all of the clones in diagonal 24 of the first eight plates belong to pool number 88. Similarly, the diagonal pools from the second superpool will be in pools numbered 152-176. This would continue in a similar fashion until all of the superpools belong to diagonal pools and each are assigned unique numbers.

[0046] To see one design of many possible schemes for identifying a complete set unique pool numbers, please see Table 7. Table 7 is designed for 88 pools in each subset (superpool) and ten subset (superpools) in the complete set. These unique pool numbers are used to construct various tested screening pool pooling strategies.

[0057] Tables 13, 14, 15 and 16 show data collected form various pooling designs.

[0058] In order to facilitate quick and accurate analysis of user screening data, we have developed a computer program which identifies the appropriate plate and well position of all potential positive clones. The results will be processed with error correction algorithms to enhance the reliability of the results and compensate for false negative data and false positive data (inherent in many screening technologies like PCR). The results will be displayed as probability scores indicating the likelihood of the resulting plate and well position being correct.

[0059] While the invention has been described with reference to more than one preferred embodiment, it is to be clearly understood by those skilled in the art that the invention is not limited thereto to these two embodiments. The general concept of separating the large library set into multiple superpools and then making one, or more than one, set(s) of matrix pools formed by re-pooling a subset of the unique pools into screening pools that will be screened. Each unique pool can be placed in 0, 1 or more than one screening pools, depending on the redundancy of identification required.

Claims

1. A method of pooling a number of subsets of a complete set in which each subset is pooled in a similar fashion and the intermediate pools from these subsets are then further pooled into screening pools for the complete set.

2. A method as claimed in claim 1 in which the complete set is a genomic DNA library, cDNA library, RNA library, cellular metabolite library, chemical compound library, protein library, antibody library, other collection of materials that could be defined as ‘a library’ by being composed of a collection of individual samples or subsets of samples.

3. A method as claimed in claim 1 in which each subset is a collection containing different biological or chemical materials of unique or redundant items.

4. A method as claimed in claim 1 in which the intermediate pools are further pooled in a matrix design which reduces the overlap while maintaining the ability to identify individual unique samples in the library or collection.

5. A method as claimed in claim 1 in which the intermediate pools are further pooled in an design compatible with error correction technologies which allow the correct identification of unique wells/samples even if false positive or false negative errors occur.

6. A method as claimed in claim 1 in which the screening pools are screened by any method which allows the identification of one or more than one unique characteristics of the biological or chemical material.

7. A method of designing the scheme to further pool the intermediate pools in which the number of screened pools needed are reduced while maintaining the ability to identify unique wells.

8. A method of identifying the unique well by using a look-up table or a mathematical formula together with a computer program to identify the unique well.

9. A method as claimed in claim 8 in which a probability score of the correct unique well identification is given and the probability score of other possible unique wells that are similar is also given.

10. A method as claimed in claim 8 in which the probability is based on the random occurrence of false positive or false negative signals.
