Summary: Cat.No.: Kit-1274 Product Overview: β-Arrestin GPCR cells are engineered to co-the ProLink (PK) tagged GPCR and the Enzyme Acceptor (EA) tagged β-Arrestin. Activation of the GPCR-PK induces β-Arrestin-EA recruitment, forcing complementation of the two β-galactosidase enzyme fragments (EA and PK). The resulting functional enzyme hydrolyzes substrate to generate a chemiluminescent signal. These cells have been modified to prevent long term propagation and expansion using a proprietary compound that has no apparent effect on assay performance. Size: 100 dp(1 x 96-well)/200 dp(2 x 96-well)/1000 dp(10 x 96-well) Target Species: Human Storage: Short term (2 weeks): Store in vapor phase of liquid N2 Kit Components: 1.25 x 10^6 cells per vial in 0.1 mL (kit contains cells, detection reagents and plate(s))
