Ready-to-Assay FFA3/GPR41 Free Fatty Acid Receptor Frozen Cells

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.

GPR41 is a GPCR that, along with GPR43, is activated by short chain carboxylic acids formate, acetate, proprionate, butyrate and pentanoate (Brown et al., 2003; Brown et al., 2005). Binding of these ligands to GPR41 selectively activates Gi to inhibit cAMP accumulation. Expression of GPR41 is prominent in adipose tissue, increases during differentiation of cultured adipocytes, and allows short chain carboxylic acids to stimulate leptin synthesis in adipocytes (Xiong et al., 2003) Millipore′s cloned human GPR41-expressing cell line is made in the Chem-4 host, which supports high levels of recombinant GPR41 expression on the cell surface and contains optimized levels of a recombinant promiscuous G protein 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 GPR41 (FFA3).
