DiscoverX PathHunter™ eXpress mRXFP3 CHO-K1 β-Arrestin GPCR Assay

The PathHunter™ mRXFP3 β-Arrestin 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. relaxin-3) based activation of mRXFP3 GPCR activity via detection of β-arrestin recruitment. This product uses EFC technology (www.discoverx.com/technologies-platforms/enzyme-fragment-complementation-technology). The included cells overexpress PK-tagged mRXFP3 and EA-tagged β-Arrestin 2. Activation of mRXFP3 stimulates the recruitment of β-Arrestin 2 and produces EFC signal. 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.
