Abstract
The present invention describes an encoded combinatorial chemical library comprised of a plurality of bifunctional molecules having both a chemical polymer and an identifier oligonucleotide sequence that defines the structure of the chemical polymer. Also described are the bifunctional molecules of the library, and methods of using the library to identify chemical structures within the library that bind to biologically active molecules in preselected binding interactions.
Claims5
A method for identifying a biochemical polymer that participates in a preselected binding interaction with a biologically active molecule to form a binding reaction complex, the method comprising the steps of:
- a) providing a library of bifunctional molecules, each bifunctional molecule having the formula A-B-C, wherein A is the biochemical polymer, B is a linker molecule operatively linked to A and C, and C is an identifier oligonucleotide comprising a sequence of nucleotides which encodes and identifies the biochemical polymer A;
- then
- b) admixing in solution said library of bifunctional molecules of said step (a) with the biologically active molecule under binding conditions for a time period sufficient to form the binding reaction complex;
- then
- c) isolating the bindinq reaction complex formed in said step (b);
- then
- d) amplifying the identifier oligonucleotide C of the bifunctional molecule within the binding reaction complex isolated in said step (c) by means of PCR;
- and then
- e) sequencing and decoding the identifier oligonucleotide C amplified in said step (d) for identifying the biochemical polymer that participated in the preselected binding interaction.
