Anti-Selenoprotein W, 1 antibodies enable researchers to detect and measure the Selenoprotein W, 1 antigen in biological samples. This target is a reported synonym of the SELENOW gene, which encodes selenoprotein W. This protein is reported to play a role as a glutathione (GSH)-dependent antioxidant. The human version of Selenoprotein W, 1 has a canonical amino acid length of 87 residues and a protein mass of 9.4 kilodaltons. It is reported to be localized in the cytoplasm of cells. Other names for this target antigen include SEPW1, selW, and selenoprotein W, 1.
