Abstract

Dimeric oligopeptide mixture sets, their synthesis and use in determining the sequence of an oligopeptide dimer ligand that optimally binds to a receptor are disclosed. A dimeric oligopeptide mixture set has two oligopeptide portions bonded together by a disulfide bond. Each oligopeptide of a first oligopeptide portion has the same number of 3 to about 10 residues including an oxidized mercaptan-containing residue that forms part of the disulfide bond and an amino acid residue sequence that includes at least one of at least six residues in addition to the oxidized mercaptan-containing residue at the same one or more predetermined positions of the oligopeptide chain. The second portion has an oligopeptide chain having a length of 4 to about 10 residues, including an oxidized mercaptan-containing residue that forms part of the disulfide bond. The second portion is a mixture whose chains have equimolar amounts of those at least six amino acid residues at the same one or more other positions of the oligopeptide chain.
