Anti-PLA2G4D antibodies are used in the immunodetection of the protein phospholipase A2 group IVD. In humans, the canonical protein has a reported length of 818 amino acid residues and a mass of 92 kDa. Its subcellular localization is in the membrane and cytoplasm. Up to 2 different isoforms have been reported for this protein. It is reported to be expressed in stratified squamous epithelia, such as those in skin and cervix, but not in other tissues. PLA2G4D is known to be involved with fatty acid metabolism and the metabolism of lipids. Synonyms for this target antigen include cPLA2-delta, phospholipase A2 delta, cytosolic, phospholipase A2, group IVD (cytosolic), and cytosolic phospholipase A2 delta. PLA2G4D gene orthologs have been reported in the mouse, rat, bovine, frog and chimpanzee species. Immunohistochemistry is the most common application for the PLA2G4D antibodies listed below. ELISA and Western Blot are also common applications.
