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.
Prostanoids are a series of arachidonic acid metabolites produced by the action of cyclooxygenase and subsequently by isomerases and synthases. Cells rapidly secrete prostanoids after synthesis, whereupon the prostanoids bind to a family of 8 GPCRs to exert their biological effects (Narumiya and FitzGerald, 2001). The prostaglandin PGE2 causes pain, vasodilation, immunosuppression of T cells, bone resorption and promotion of carcinogenesis. Four related GPCRs, EP1, EP2, EP3 and EP4, each bind to PGE2, but the different G protein coupling status of each receptor leads to distinct biological effects; EP1 couples primarily to Gq to mobilize intracellular calcium. EP1 appears to mediate the effects of PGE2 in promoting formation of precancerous lesions in animal models of colon cancer (Watanabe et al., 1999). In addition, EP1 has an inhibitory effect on stress-induced aggressive and risk-taking behaviors in mice (Matsuoka et al., 2005). Chemicon′s cloned human EP1-expressing cell line is made in the Chem-1 host, which supports high levels of recombinant EP1 expression on the cell surface and contains high levels of the promiscuous G protein Galpha15 to enhance coupling of the receptor to the calcium signaling pathway.
