The PathHunter CHO-K1 GLP2R Bioassay Kit provides an easy-to-use cell based assay to measure drug potency and detect neutralizing antibodies. This bioassay asseses ligand (e.g. Recombinant Human Complement C5a) based on activation of GLP2R GPCR activity via detection of β-Arrestin recruitment. The included cell line overexpresses ProLink-tagged GLP2R and EA-tagged β-Arrestin-2. Activation of GLP2R stimulates the recruitment of β-Arrestin-2 and produces EFC signal. Bioassay 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, control agonist, detection reagent, and assay plates.
