Anti-PON2 antibodies are used in the immunodetection of the protein paraoxonase 2. In humans, the canonical protein has a reported length of 354 amino acid residues and a mass of 39.4 kDa. Its subcellular localization is in the membrane. Up to 3 different isoforms have been reported for this protein. It is reported to be widely expressed with highest expression in the liver, lung, placenta, testis and heart. A member of the Paraoxonase protein family, PON2 is known to be involved with the response to oxidative stress. Synonyms for this target antigen include A-esterase 2, aromatic esterase 2, arylesterase 2, paraoxonase nirs, serum aryldialkylphosphatase 2, and serum paraoxonase/arylesterase 2. PON2 gene orthologs have been reported in the mouse, bovine, frog and chimpanzee species. A number of PON2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
