Biological Information
Background Information:
The PathHunter® C5AR1 Activated GPCR internalization eXpress kit provides an easy to-use cell based assay to study drug candidates affecting GPCR activation and internalization. This kit assesses ligand (e.g. C5a) based internalization of C5AR1 via detection of localization to the early endosome. This product uses EFC technology. The cells included overexpress EA-tagged β-arrestin 2 as well as a PK-tagged early endosome protein and untagged C5AR1. Upon ligand-induced receptor activation, β-arrestin 2 is recruited to the activated GPCR and the resulting C5AR1-arrestin complex is internalized to the early endosome, leading to production of 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.
