Ready-to-Assay™ OX1 Orexin Receptor Frozen Cells

The Ready-to-Assay™ OX1 Orexin Receptor Frozen Cells measure HCRTR1 (GPCR) activation via an increase in intracellular calcium. Ready-to-Assay kits contain two vials of thaw-and-use cells.

Catalog #: HTS175RTA Size: 2 vials


Biological Information
Background Information:
The Ready-to-Assay™ OX1 Orexin 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. orexins) based activation of HCRTR1 GPCR activity via detection of increasing levels of intracellular calcium. The included cells overexpress HCRTR1 alongside endogenous high levels of a promiscuous G-protein, coupling the receptor to the calcium signaling pathway. Upon activation of HCRTR1 , 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.
