Abstract
Methods are described for studying .mu., .delta. and .kappa. opioid binding sites, each without interference from the others. A large array of ligands have been characterized by ligand selectivity profiles, graphic depictions of affinities and selectivities. Binding site signatures have been derived, which uniquely describe each of the three types of sites. The .mu., .delta., and .kappa. binding sites have interesting common features and distinctive differences.
