Western blot shows lysates of human CD4+ T Cells and human liver tissue. PVDF Membrane was probed with 1 µg/mL of Sheep Anti-Human Cytosolic Sulfotransferase 1B1/SULT1B1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5959) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for Cytosolic Sulfotransferase 1B1/SULT1B1 at approximately XXX kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group XXX.
