Claims
- 1. Nucleic acid ligands that bind covalently with a protein, wherein said nucleic acid ligands comprise a chemically reactive functional unit, wherein said nucleic acid ligands are produced by the method comprising the steps of:
- a) preparing a candidate mixture of nucleic acids;
- b) contacting the candidate mixture with said protein, wherein nucleic acids which bind covalently with said protein may be partitioned from the remainder of the candidate mixture;
- c) partitioning the nucleic acids that bind covalently with the protein from the remainder of the candidate mixture; and
- d) amplifying the nucleic acids that bind covalently with the protein, whereby nucleic acid ligands that bind covalently with the protein may be produced.
- 2. The nucleic acid ligands of claim 1 which are selected from the sequences listed in Table VI (SEQ ID NOS: 108-224).
- 3. A facilitating nucleic acid, wherein said nucleic acid comprises a chemically reactive functional unit, identified according to the method comprising the steps of:
- a) preparing a candidate mixture of nucleic acids;
- b) contacting the candidate mixture with a protein, wherein nucleic acids having a facilitating activity, as indicated by a covalent bond being formed between said protein and said nucleic acid, relative to the candidate mixture may be partitioned from the remainder of the candidate mixture;
- c) partitioning the nucleic acids having a facilitating activity from the remainder of the candidate mixture; and
- d) amplifying the nucleic acids having a facilitating activity, whereby a facilitating nucleic acid may be identified.
- 4. A method for partitioning nucleic acids from a nucleic acid candidate mixture, wherein said nucleic acid ligands comprise a chemically reactive functional unit, said method comprising:
- a) preparing a nucleic acid candidate mixture;
- b) contacting the nucleic acid candidate mixture with a protein under conditions wherein nucleic acids form a covalent bond with said protein; and
- c) partitioning away the remainder of the nucleic acid candidate mixture which did not form a covalent bond with the protein, leaving only nucleic acids which have formed a covalent bond with the protein.
- 5. A purified and isolated non-naturally occurring nucleic acid ligand which binds covalently with a protein, wherein said nucleic acid ligand comprises a chemically reactive functional unit.
