Methods for screening factorial chemical libraries
First Claim
1. A method of identifying first and second monomers in a polymer that specifically binds to a receptor of interest, said polymer selected from the group consisting of oligonucleotides and peptides, comprising the steps of:
- coupling first and second monomers in a first basis set to individual solid substrates and mixing substrates to form first pooled products;
coupling said first and second monomers from said first basis set to individual substrates, and not mixing said substrates to form at least first and second separate products;
separately coupling first and second monomers from a second basis set to substrates from said first pooled products and not mixing said substrates to form at least third and fourth separate products;
coupling said first and second monomers from said second basis set to individual substrates from said first separate products and mixing said substrates to form second pooled products;
coupling said first and second monomers from said second basis set to individual substrates from said second separate products to form third pooled products; and
exposing a receptor to said third and fourth separate products to identify a second monomer in a polymer which is complementary to a receptor, and exposing said second and third pooled products to said receptor to identify a first monomer in a polymer which specifically binds to said receptor.

Abstract
A method and library for determining the sequence of monomers in a polymer which is complementary to a receptor. The method provides for formation of pooled (6) and separate (10, 12) products. Separate products are subjected only to subsequent pooled coupling steps. Each pooled product is subsequently divided for formation of pooled and separate products. The resulting polymer library includes groups of polymer products. A first group of products (42) is used to identify the monomer at a first location in a polymer that is complementary to a receptor. A second group of products (44) is used to identify the monomer at a second location in a polymer that is complementary to a receptor.
