Anti-HS2ST1 antibodies are used in the immunodetection of the protein heparan sulfate 2-O-sulfotransferase 1. In humans, the canonical protein has a reported length of 356 amino acid residues and a mass of 41.9 kDa. Its subcellular localization is in the Golgi. Up to 3 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the Sulfotransferase 3 protein family, Hs2st1 is known to catalyze the transfer of sulfate to the C2-position of selected hexuronic acid residues within the maturing heparan sulfate (HS). Post-translational modifications have been described, including N-glycosylation. Synonyms for this target antigen include dJ604K5.2, 2-O-sulfotransferase, 2OST, and NFSRA. HS2ST1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Western Blot is the most common application for the Hs2st1 antibodies listed below. ELISA and Immunohistochemistry are also common applications.
