The PathHunter GCGR cell line is a stable, engineered cell line for use in studying drug candidates (small molecules or biologics) targeting GPCRs. This cell line enables assessment of ligand (e.g. glucagon) based activation of GCGR GPCR activity via detection of β-arrestin recruitment. The included cell line overexpresses ProLink-tagged GCGR and EA-tagged β-Arrestin-2. Activation of GCGR stimulates the recruitment of β-Arrestin-2 and produces EFC signal. This stable modified cell line is provided as two vials of cryopreserved cells. For detailed product information, User Manual and datasheet, visit www.discoverx.com/gpcr.
