immortal cell line cell immortal cell line cell 永生细胞系细胞 PathHunter CHO-K1 DRD2L Beta-Arrestin cell 624495 BAO, YH BAO: BAO_0030056 A PathHunter Beta-Arrestin GPCR cell line (DiscoverX), engineered to co-express the ProLink (PK) tagged GPCR (DRD2L, long form of human DRD2) and the Enzyme Acceptor (EA) tagged Beta-Arrestin. Activation of DRD2L-PK induces Beta-Arrestin-EA recruitment, forcing complementation of the two Beta-galactosidase enzyme fragments (EA and PK). The resulting functional enzyme hydrolyzes substrate to generate a chemiluminescent signal. https://www.discoverx.com/products/cell-line/cho-k1-drd2l-beta-arrestin-cell-line-93-0579c2
