Anti-GPX7 antibodies are used in the immunodetection of the protein glutathione peroxidase 7. In humans, the canonical protein has a reported length of 187 amino acid residues and a mass of 21 kDa. It has been described to be a secreted protein. It is reported to be expressed in esophageal epithelial cells; expression is up-regulated after exposure to acidic bile acids. A member of the Glutathione peroxidase protein family, GPX7 is known to be involved with the response to oxidative stress. The GPX7 gene has been associated with the disease, Barrett esophagus. Synonyms for this target antigen include GPX6, GSHPx-7, NPGPx, non-selenocysteine containing phospholipid hydroperoxide glutathione peroxidase, and CL683. GPX7 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of GPX7 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.
