The PathHunter mEDG1 cell line is a stable, engineered cell line for use in studying drug candidates (small molecules or biologics) targeting GPCRs. This cell line enables assessment of ligand (e.g. S1P) based activation of mEDG1 GPCR activity via detection of β-arrestin recruitment. The included cell line overexpresses ProLink-tagged mEDG1 and EA-tagged β-Arrestin-2. Activation of mEDG1 stimulates the recruitment of β-Arrestin-2 and produces EFC signal. This stable modified cell line is provided as two vials of cryopreserved cells. Please note that this product expresses the Mouse version of this protein.
