Ready-to-Assay™ GPR103/Peptide P518 Receptor Frozen Cells

The Ready-to-Assay™ GPR103/Peptide P518 Receptor Frozen Cells measure QRFPR (GPCR) activation via an increase in intracellular calcium. Ready-to-Assay kits contain two vials of thaw-and-use cells.

Catalog #: HTS189RTA Size: 2 vials


Biological Information
Background Information:
The Ready-to-Assay™ GPR103/Peptide P518 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. QRFP neuropeptides) based activation of QRFPR GPCR activity via detection of increasing levels of intracellular calcium. The included cells overexpress QRFPR alongside endogenous high levels of a promiscuous G-protein, coupling the receptor to the calcium signaling pathway. Upon activation of QRFPR , the resulting calcium activity can be fluorescently assayed. Ready-to-assay kits consist of two vials of the stably modified clonal cell line in a convenient thaw-and-use format.
