Anti-GPR43 antibodies enable researchers to detect and measure the GPR43 antigen in biological samples. This target is a reported synonym of the FFAR2 gene, which encodes free fatty acid receptor 2. This protein is known to function in fat cell differentiation and GPCR signaling pathways, among other biological roles. The human version of GPR43 has a canonical amino acid length of 330 residues and a protein mass of 37.1 kilodaltons. It is reported to be localized in the cell membrane of cells and notably expressed in the spleen, lung, caudate, and bone marrow. Other names for this target antigen include FFA2R and FFA2R. Indicated applications for GPR43 antibodies listed below include ELISA, Western Blot, and Immunofluorescence.
