DiscoverX PathHunter™ eXpress GHSR1a U2OS β-Arrestin-1 GPCR Assay

The PathHunter™ GHSR1a (ARR1) 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. ghrelin) based activation of GHSR1a 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 GHSR1a and EA-tagged β-Arrestin-1. Activation of GHSR1a stimulates the recruitment of β-Arrestin-1 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.
