Quantitative electron microscopic autoradiography of insulin, glucagon, and somatostatin binding sites on islets

YC Patel, M Amherdt, and L Orci

After monolayer cultures of rat islets were exposed to [125I]insulin,[125I]glucagon, and [125I]tyrosinyl somatostatin, specific autoradiographic grains associated with each radioactively labeled ligand were found on B, A, and D cells.The density of labeling of the B, A, and D cells with each labeled ligand correlated well with the known actions of the three hormones on each of the islet cells.
