title: Solubilization of adrenal angiotensin II receptors with a zwitterionic detergent.
abstract: Active rat adrenal angiotensin II receptors have been solubilized with a zwitterionic detergent, 3 [(3-cholamidopropyl)-dimethylammonio] -1-propane sulfonate. The solubilized receptors retain a high affinity for angiotensin II (Kd = 1.9 nM) similar to the value observed in adrenal membrane particles (Kd = 1.2 nM). In addition, the binding-inhibition potency of several angiotensin II peptides is maintained unaltered, indicating a fully preserved specificity of the solubilized receptors.
