(-)-CGP-12177 is a high affinity antagonist of both β1- and β2-adrenoceptors, and functions as a partial agonist at β3-adrenoceptors. These receptors are part of a group of beta adrenergic G-protein coupled receptors (GPCRs) found in adipose tissue, heart tissue, and vascular smooth muscle tissue that play a role in cardiac output, hormone release, smooth muscle relaxation, and lipolysis. Beta adrenergic receptors have been identified as potential drug targets for congestive heart failure, hypertension, asthma, COPD, and neoplasia.

We offer both agonist and antagonist radioligands for autoradiographic visualization or performing saturation and competition assays to determine receptor expression levels (B_max), dissociation constants (K_d), association and dissociation rates (k_on and k_off), and inhibitor constants (K_i) for a variety of receptors. We develop our radioligands to the highest specific activity possible and provide high purity resulting in low non-specific binding products. Each of our ultra-pure radioligands is fully characterized for pharmacological action and validated in receptor binding assays.

Radiolabeled ligands remain the most sensitive method for probing receptor binding biology; yielding unprecedented sensitivity gives results that technicians and scientists can trust. For over 50 years, Revvity has been a leading supplier of New England Nuclear (NEN) radiochemicals, liquid scintillation cocktails, vials and nuclear counting detection instruments.
