General description

Millipore’;s Ready-to-Assay GPCR frozen cells are designed for simple, rapid calcium assays with no requirement for intensive cell culturing. Millipore has optimized the freezing conditions to provide cells with high viability and functionality post-thaw. The user simply thaws the cells and resuspends them in media, dispenses cell suspension into assay plates and, following over night recovery, assays for calcium response.

The Mas-related gene family (Mrg), also known as SNSR (sensory neuron-specific G protein-coupled receptors), are expressed mainly in the dorsal root ganglia and appear to be involved in nociception and other sensory processes. MRGPRX1/SNSR4 is activated by the neuropeptide BAM22, and it mediates neuronal synaptic transmission and ion channel activity (Lembo et al., 2002; Burstein et al., 2006, Chen and Ikeda, 2004). Millipore’;s cloned human MRGPRX1-expressing cell line is made in the Chem-1 host, which supports high levels of recombinant MRGPRX1 expression on the cell surface and contains high levels of the promiscuous G protein Gα15 to couple the receptor to the calcium signaling pathway. Thus, the cell line is an ideal tool for screening for agonists, antagonists, and modulators at MRGPRX1.
