Pentazocine functions as a sigma σ1 receptor agonist, where it has been shown to inhibit the outward current of potassium ions (K+). It is a known analgesic used to treat pain.

We offer both agonist and antagonist radioligands for autoradiographic visualization or performing saturation and competition assays to determine receptor expression levels (Bmax), dissociation constants (Kd), association and dissociation rates (kon and koff), and inhibitor constants (Ki) 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, PerkinElmer has been a leading supplier of New England Nuclear (NEN) radiochemicals, liquid scintillation cocktails, vials and nuclear counting detection instruments.

GPCRs: The Pathway to Discovery

G protein coupled-receptors (GPCRs) are one of the most intensively studied drug targets, with up to one-third of all marketed therapeutics acting by binding to GPCRs. Therapies that target GPCRs include both agonist and antagonists that are used in the treatment of disease in nearly every major ...
