HEK293 cells stably expressing CB1 Cannabinoid Receptor, cAMP biosensor & β-arrestin biosensor

Description Gentaur Cells are cell lines stably co-expressing tag-free GPCRs and two Gentaur Biosensors to monitor G-protein and β-arrestin modulation. Each vial of Gentaur CB1 Cannabinoid Receptor Cell Line contains HEK293 cells stably expressing the following constructs: human α1B-adrenoceptor with no tag cAMP Gentaur Biosensor (Red Fluorescence) β-arrestin Gentaur Biosensor (Green Fluorescence) Gentaur CB1 Cannabinoid Receptor Cell Line allows to assay compounds analyzing both signalling pathways involving receptor activation; G protein by cAMP flux and β-arrestin recruitment, hence allowing biased activity studies. When an agonist binds to CB1 a G protein is activated which, in turn, triggers a cellular response mediated by cAMP and a subsequent internalization mediated by ß-Arrestin. This leads to an increase of fluorescence intensity of both β-Arrestin and cAMP biosensors. So, the activity can be easily quantified on living cells in a dose-response manner by fluorescence emission in a microplate reader.
