Motif Libraries

A library consisting of a multiplicity of sets, each said set comprising a multiplicity of species of test ligands, in which:

• a) each species of test ligand of the library comprises a linker and a multiplicity of monomers, wherein:
• i) said monomers are selected from a multiplicity of species of monomers;
• and
• ii) said linker connects the monomers of a species of test ligand to a solid phase support particle or to an identifiable location of a solid support;
• b) each monomer is disposed in one of a predetermined number of motif positions or in one of a predetermined or variable number of nonmotif positions, wherein:
• i) the motif and non-motif positions have an ordered sequence;
• and
• ii) there are a plurality of motif positions in each set of the library;
• c) all species of test ligands of a particular set have:
• i) a constant number of nonmotif positions and an identical, single ordered sequence of motif and nonmotif positions;
• ii) an identical, single species of monomer, selected from a plurality of species of monomer, at each of the predetermined number of motif positions;
• and
• iii) one of a plurality of species of monomers at each of the constant number of nonmotif positions;
• d) all species attached to a particular solid phase particle or to a particular identifiable location of a solid support are encompassed by a single set;
• and
• e) the library is a complete collection of sets in which all possible particular ordered
• (i) sequences of the motif positions and nonmotif positions or
• (ii) sequences of motif positions and intervals of nonmotif positions are represented.
