Biological Information
Background Information:
The PathHunter® F2RL1 (PAR2; GPR11) 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. proteases, SLIGRL) based activation of F2RL1 GPCR activity via detection of β-arrestin recruitment. This product uses EFC technology. The cells included overexpress PK-tagged F2RL1 and EA-tagged β-Arrestin-2. Activation of F2RL1 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.
