Anti-SULT1B1 antibodies are used in the immunodetection of the protein sulfotransferase family 1B member 1. In humans, the canonical protein has a reported length of 296 amino acid residues and a mass of 34.9 kDa. Its subcellular localization is in the cytoplasm. It is reported to be highly expressed in the liver, peripheral blood leukocytes, colon (mucosal lining), small intestine (jejunum) and spleen. A member of the Sulfotransferase 1 protein family, SULT1B1 is a reported sulfotransferase that utilizes 3'-phospho-5'-adenylyl sulfate (PAPS) as sulfonate donor to catalyze the sulfate conjugation of dopamine, small phenols such as 1-naphthol and p-nitrophenol and thyroid hormones, including 3,3'-diiodothyronine, triidothyronine (T3) and reverse triiodothyronine (rT3). Synonyms for this target antigen include ST1B2, SULT1B2, sulfotransferase 1B1, sulfotransferase 1B2, sulfotransferase family, cytosolic, 1B, member 1, and ST1B1. Some SULT1B1 antibodies may have been used in research and have associated citations. ELISA, Western Blot, and Immunohistochemistry are common applications for these antibodies.
