Anti-PLA2G12B antibodies are used in the immunodetection of the protein phospholipase A2 group XIIB. In humans, the canonical protein has a reported length of 195 amino acid residues and a mass of 21.7 kDa. It has been described to be a secreted protein. Up to 2 different isoforms have been reported for this protein. It is reported to be highly expressed in the liver, small intestine and kidney. A member of the Phospholipase A2 protein family, PLA2G12B is known to be involved with cholesterol metabolism and homeostasis and the metabolism of lipids. Synonyms for this target antigen include group XIII secreted phospholipase A2, phospholipase A2, group XIII, and group XIIB secretory phospholipase A2-like protein. PLA2G12B gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. These PLA2G12B antibodies are widely used in Western Blot experiments, among other applications.
