Anti-PIGH antibodies are used in the immunodetection of the protein phosphatidylinositol glycan anchor biosynthesis class H. In humans, the canonical protein has a reported length of 188 amino acid residues and a mass of 21.1 kDa. Its subcellular localization is in the cytoplasm. It is notably widely expressed in many tissue types. A member of the PIGH protein family, PIGH is known to be a part of the glycosylphosphatidylinositol-N-acetylglucosaminyltransferase (GPI-GnT) complex that catalyzes the transfer of N-acetylglucosamine from UDP-N-acetylglucosamine to phosphatidylinositol and participates in the first step of GPI biosynthesis. Synonyms for this target antigen include phosphatidylinositol N-acetylglucosaminyltransferase subunit H, phosphatidylinositol-glycan biosynthesis, class H protein, and GPI-H. PIGH gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. ELISA is the most common application for the PIGH antibodies listed below. Western Blot and Immunohistochemistry are also common applications.
