title: Subclass specificity of anti-idiotypic anti-opiate receptor antibodies in rat brain, guinea pig cerebellum, & neuroblastoma x glioma (NG 108-15).
abstract: Receptor subclass recognition properties of affinity-purified rabbit polyclonal anti-idiotypic anti-opiate receptor antibodies in various membrane preparations have been determined. The anti-receptor immunoglobulins significantly decrease binding of 3H-[D-Ala2,-MePhe4,Gly-ol5]enkephalin, a highly selective mu agonist, in rat neural membrane. In the presence of a concentration of the unlabeled ligand sufficient to block existing mu sites, the antibodies compete, to a lesser degree with 3H-[D-Ala2,D-Leu5]enkephalin for delta site occupancy in both rat neural membrane, and neuroblastoma x glioma membrane preparations. The antibodies do not displace 3H-ethylketocyclazocine from rat brain or guinea pig cerebellum.
