Anti-CHST8 antibodies are used in the immunodetection of the protein carbohydrate sulfotransferase 8. In humans, the canonical protein has a reported length of 424 amino acid residues and a mass of 48.8 kDa. Its subcellular localization is in the Golgi. It is reported to be highly expressed in the pituitary gland. A member of the Sulfotransferase 2 protein family, CHST8 is known to catalyze the transfer of sulfate to position 4 of non-reducing N-acetylgalactosamine (GalNAc) residues in both N-glycans and O-glycans. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include GalNAc-4-O-sulfotransferase 1, N-acetylgalactosamine-4-O-sulfotransferase 1, carbohydrate (N-acetylgalactosamine 4-0) sulfotransferase 8, galNAc4ST-1, and GALNAC-4-ST1. CHST8 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some CHST8 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
