Anti-Glutathione Peroxidase 2 antibodies are used for the immunodetection of the protein encoded by the GPX2 gene. In humans, the canonical protein has a reported length of 190 amino acid residues and a mass of 22 kDa. Its subcellular localization is in the cytoplasm. A member of the Glutathione peroxidase protein family, it is suspected to be play a major role in protecting mammals from the toxicity of ingested organic hydroperoxides. Other names for this target antigen include GPRP, GPRP-2, GPx-GI, GSHPX-GI, GSHPx-2, and GI-GPx. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 70 citations in the literature describe the use of Glutathione Peroxidase 2 antibodies in research. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
