Detection of Human Cytosolic Sulfotransferase 1C2/SULT1C2 by Western Blot. Western blot shows lysates of Caki‑2 human clear cell carcinoma epithelial cell line. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Human Cytosolic Sulfotransferase 1C2/ SULT1C2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF7458) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for Cytosolic Sulfotransferase 1C2/SULT1C2 at approximately 35 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Cytosolic sulfotransferases catalyze the sulfonation of many hormones, neurotransmitters, drugs, and xenobiotic compounds. They are distinct from Golgi-resident sulfotransferases by the absence of transmembrane domains and are located in the cytoplasm (1, 2). SULT1C2 is mainly expressed in the gastrointestinal tract (stomach, duodenum, jejunum, ileum, colon, caecum and rectum), liver and kidneys, but not in the lungs (3). In contrast, SULT1C4, a sulfotransferase that is most closely related to SULT1C2 (4), is expressed at higher levels in fetal lung and kidney and at lower levels in fetal heart. So far, SULT1C2 is found to be active only on p-nitrophenol (3). The enzymatic activity of our recombinant human SULT1C2 was determined using a phosphatase-coupled assay (5).
