Anti-HS3ST3B1 antibodies are used in the immunodetection of the protein heparan sulfate-glucosamine 3-sulfotransferase 3B1. In humans, the canonical protein has a reported length of 390 amino acid residues and a mass of 43.3 kDa. Its subcellular localization is in the Golgi. It is ubiquitously expressed across many tissue types. A member of the Sulfotransferase 1 protein family, HS3ST3B1 is a reported sulfotransferase that utilizes 3'-phospho-5'-adenylyl sulfate (PAPS) to catalyze the transfer of a sulfo group to an N-unsubstituted glucosamine linked to a 2-O-sulfo iduronic acid unit on heparan sulfate. Synonyms for this target antigen include 3OST3B1, h3-OST-3B, heparan sulfate glucosamine 3-O-sulfotransferase 3B1, heparan sulfate (glucosamine) 3-O-sulfotransferase 3B1, and 3-OST-3B. HS3ST3B1 gene orthologs have been reported in the mouse, rat and chimpanzee species. Some HS3ST3B1 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. Immunocytochemistry and Immunofluorescence are also common applications.
