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 .
