125I-labeled p-azidobenzylcarazolol, a photoaffinity label for the beta-adrenergic receptor. Characterization of the ligand and photoaffinity labeling of beta 1- and beta 2-adrenergic receptors.

Abstract

Previous reports fromour laboratories have described two approaches to photoaffinity labeling of the P2-adrenergic receptor of the frog erythrocyte.First, [3H]p-azidobenzylcarazolol could be directly incorporated into partially purified preparations of the receptor (Lavin, T. N.,
