Anti-BCAT2 antibodies are used in the immunodetection of the protein branched chain amino acid transaminase 2. In humans, the canonical protein has a reported length of 392 amino acid residues and a mass of 44.3 kDa. Its subcellular localization is in the mitochondria. Up to 2 different isoforms have been reported for this protein. It is ubiquitously expressed across many tissue types. A member of the Class-IV pyridoxal-phosphate-dependent aminotransferase protein family, BCAT2 is known to catalyze the first reaction in the catabolism of the essential branched chain amino acids leucine, isoleucine, and valine. Synonyms for this target antigen include BCATM, BCT2, HVLI, PP18, branched-chain-amino-acid aminotransferase, mitochondrial, and BCAM. BCAT2 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. Over 70 citations in the literature describe the use of BCAT2 antibodies in research. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
