Anti-A4GNT antibodies are used in the immunodetection of the protein alpha-1,4-N-acetylglucosaminyltransferase. In humans, the canonical protein has a reported length of 340 amino acid residues and a mass of 39.5 kDa. Its subcellular localization is in the Golgi. It is notably expressed in the stomach and pancreas. A member of the Glycosyltransferase 32 protein family, A4GNT is known to catalyze the transfer of N-acetylglucosamine (GlcNAc) to core 2 branched O-glycans. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include alpha4GnT. A4GNT gene orthologs have been reported in the mouse, rat, bovine, chimpanzee and chicken species. Some A4GNT antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
