Binding of antimorphine anti-idiotypic antibodies to opiate receptors.
Antibodies that specifically recognize and bind opiate receptors were developed by the anti-idiotypic method. Antimorphine antibodies were generated in rabbits and showed selective binding to various opiate ligands. Guinea pigs were immunized with antimorphine antibodies to produce anti-idiotypic antibodies that cross-reacted with opiate receptors. Guinea pig antiserum inhibited binding of naloxone (0.6 nmol) to mouse brain homogenate. In isolated mouse vas deferens, contraction of electrically stimulated tissue was inhibited by the antiserum. The results indicate that anti-idiotypic antibodies which interact with opiate receptors were developed without isolating receptors.
