Anti-Glutathione Peroxidase 1 antibodies are used for the immunodetection of the protein encoded by the GPX1 gene. In humans, the canonical protein has a reported length of 203 amino acid residues and a mass of 22.1 kDa. Its subcellular localization is in the cytoplasm. Alternative splicing is reported to yield 2 different isoforms for this protein. It is reported to be expressed in platelets. A member of the Glutathione peroxidase protein family, it is known to be involved with pathways of aging and carbohydrate metabolism and homeostasis. Other names for this target antigen include GSHPX1, GSHPx-1, cellular glutathione peroxidase, selenoprotein GPX1, and GPXD. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 160 citations in the literature describe the use of Glutathione Peroxidase 1 antibodies in research. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
