Listed are ELISA Kits for the detection of irisin, an alias name of fibronectin type III domain containing 5. The human protein, encoded by the gene FNDC5, is 212 amino acid residues long and has a mass of 23,659 daltons. However, there are up to 4 reported isoforms. This protein is reported to have a membrane and secreted cellular localization, and is glycosylated. For this target protein, ELISA kits with the following species reactivities are available: human, mouse, rat, bovine, primate, guinea pig, and other mammalian. This target may also be known as: fibronectin type III domain-containing protein 5, fibronectin type III repeat-containing protein 2, FRCP2, and irisin.
