These GPR40 ELISA kits are immunodetection tools for measuring the levels of GPR40 in biological samples. GPR40 is an alias of the human FFAR1 gene, which encodes the protein, free fatty acid receptor 1. Notably, GPR40 is known to play a role in GPCR signaling pathways and carbohydrate metabolism and homeostasis, among other functions. The FFAR1 protein is described to be 300 amino acid residues in length and 31.5 kilodaltons in mass. It is localized to the cell membrane of the cell. In terms of tissue specificity, it is notably expressed in the brain and pancreas. This protein is known to be glycosylated. Other names for this target antigen include FFA1R and GPCR40.
