Label-free functional cell-based assay technology with the sensitivity to robustly measure endogenous receptor activation in live cells. The system overcomes many of the challenges and limitations found with traditional assay formats.
The CellKey?System is a universal, label-free platform for real-time cell-based functional analysis of endogenous and recombinant receptors. The system enables the measurement of a wide range of targets in a single-assay, including all families of G-protein coupled receptors (GPCRs), as well as tyrosine kinase receptors (TKRs), adhesion molecules, and indirect measurement of ion channel activation. In particular, the system is a major breakthrough for accurate monitoring of G醝- and G醩-coupled GPCR receptors, as it overcomes many of the challenges and limitations found with the traditionally available assay formats.
The underlying technology of the system is cellular dielectric spectroscopy (CDS) an impedance based measurement that eliminates the need for labels, such as tags, dyes, or specialized reagents. By eliminating the requirement for labels, the CellKey System streamlines assay development by reducing the number of steps to be optimized, and allows users to develop one standard assay solution for multiple target classes, regardless of pathway.
The system was designed to meet the needs of drug discovery scientists-- from target identification and validation through lead optimization. It is sensitive enough to monitor ligand-mediated activation of endogenous receptors expressed in adherent or non-adherent cell lines, including primary cells. The benefit of this is the ability to generate more physiologically relevant data than obtained when using genetically and chemically manipulated cells.
While traditional technologies measure only discrete intracellular events, such as Ca2+ flux or cAMP fluctuation, the CellKey System measures the integrated response of the whole cell to receptor activation. By presenting a more complete picture of the complex pathways activated, scientists gain a better understanding of the cellular response. For example, upon detecting GPCR activation, the CellKey System generates robust and reproducible response profiles that are characteristic of G醩-, G醝- or G醧- GPCRs. This qualitative data can be used to i
