Anti-SELENOW antibodies are used in the immunodetection of the protein selenoprotein W. In humans, the canonical protein has a reported length of 87 amino acid residues and a mass of 9.4 kDa. Its subcellular localization is in the cytoplasm. It is widely expressed across many tissue types. A member of the SelWTH protein family, Selenow is reported to play a role as a glutathione (GSH)-dependent antioxidant. Synonyms for this target antigen include selW, selenoprotein W, 1, and SEPW1. SELENOW gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some Selenow antibodies may have been used in research and have associated citations. Immunohistochemistry is a widely used application for these antibodies. Western Blot and Immunofluorescence are also common applications.
