DiscoverX PathHunter™ PTGER4 Activated GPCR Internalization U2OS Cell Line

Descrizione

The PathHunter™ PTGER4 Activated GPCR internalization cell line is a stable, engineered cell line for use in studying drug candidates (small molecules or biologics) affecting GPCR activation and internalization. This cell line enables assessment of ligand (e.g. prostaglandin E2) based internalization of PTGER4 via detection of localization to the early endosome. This product uses EFC technology. The included cell line overexpresses EA-tagged β-arrestin 2 as well as a PK-tagged early endosome protein and untagged PTGER4. Upon ligand-induced receptor activation, β-arrestin 2 is recruited to the activated GPCR and the resulting PTGER4-arrestin complex is internalized to the early endosome, leading to production of EFC signal. This stable modified cell line is provided as two vials of cryopreserved cells.
