The cAMP Hunter rDRD1 eXpress kit provides an easy-to-use cell based assay to study drug candidates (small molecules or biologics) targeting GPCRs. This kit assesses ligand (e.g. dopamine, A68930) based activation of rDRD1 GPCR activity via detection of increasing levels of intracellular cAMP. This product uses EFC technology. The cells overexpress wild type rDRD1, a naturally Gs coupled GPCR. Upon activation of rDRD1, the increase in levels of intracellular cAMP leads to an increased signal from EFC when the cAMP detection kit is applied. eXpress kits are a convenient, ready-to-use format which contains all materials needed to run the assay, including single-use vials of cryopreserved cells, cell plating media, detection reagent, and assay plates.
