title: Antiidiotypic antibodies interacting with cGMP-dependent channels of frog retinal rod outer segments.
abstract: Antiidiotypic approach was used to obtain antibodies interacting with cGMP-binding site of the cGMP-activated channel of the photoreceptor cell. Monoclonal anti-BrcGMP antibodies having characteristics of binding of agonist and its analogs close to those for a natural receptor have been obtained. These antibodies were used to raise polyclonal antiidiotypic antibodies capable of interacting with a natural cGMP-receptor. Application of immunoglobulins, isolated from antiidiotypic serum, to inside-out fragments of the rod plasma membrane led to an irreversible increase of the conductance of cGMP-dependent channels.
