The Ready-to-Assay GLP-1 Receptor Frozen Cells are a simple, thaw-and-assay cell format for use in studying drug candidates (small molecules or biologics) targeting GPCRs. This assay assesses ligand (e.g. GLP-1) based activation of GLP1R GPCR activity via detection of increasing levels of intracellular calcium. The included cell line overexpresses GLP1R alongside exogenous high levels of a promiscuous G-protein, coupling the receptor to the calcium signaling pathway. ChemiBrite cells also express a clytin variant, allowing for luminescent as well as fluorescent signal detection. Upon activation of GLP1R, the resulting calcium activity can be assayed in either detection mode. Ready-to-assay kits consist of two vials of the stably modified clonal cell line in a convenient thaw-and-use format.
