title: Polyclonal anti-idiotypic opioid receptor antibodies generated by the monoclonal beta-endorphin antibody 3-E7.
abstract: Anti-idiotypic antibodies were raised in rabbits against the monoclonal beta-endorphin antibody 3-E7. These antibodies inhibit beta-endorphin binding to the 3-E7 antibody, binding of 3H-diprenorphine to solubilized opioid receptors and the binding of 125I-beta-endorphin to rat brain membranes. Exposure of NG-108CC15 hybrid cells to anti-idiotypic antibodies produces an opioid-like inhibition of PGE1-stimulated cAMP accumulation. These data suggest that the antibodies raised by the anti-idiotypic route both bind to and activate opioid receptors.
