using immunocytochemical techniques with antibodies raised to the frog erythrocyte , beta 2-adrenergic receptor , beta-adrenergic receptors were identified at the light microscopic level in regions of the rat and frog brain previously found by ligand binding and autoradiography to be richest in beta-adrenergic receptors .
