Data Examples

Detection of Human ST6GAL1 by Western Blot. Western blot shows lysates of Daudi human Burkitt's lymphoma cell line. PVDF Membrane was probed with 1 µg/mL of Goat Anti-Human ST6GAL1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5924) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for ST6GAL1 at approximately 56 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

Detection of Human ST6 Gal Sialyltransferase 1/ST6GAL1 by Simple WesternTM. Simple Western lane view shows lysates of Daudi human Burkitt's lymphoma cell line, loaded at 0.2 mg/mL. A specific band was detected for ST6 Gal Sialyltransferase 1/ST6GAL1 at approximately 64 kDa (as indicated) using 10 µg/mL of Goat Anti-Human ST6 Gal Sialyltransferase 1/ST6GAL1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5924) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). This experiment was conducted under reducing conditions and using the
12-230 kDa separation system.

Background: ST6 Gal Sialyltransferase 1/ST6GAL1

Sialic acid molecules attached to glycoproteins or glycosphingolipids play important roles in various biological processes such as immune recognition, pathogen infection, and cell adhesion (1). Sialyltransferases are key enzymes that regulate the cellular levels of sialic acid-containing molecules. Beta-galactosamide alpha‑2,6‑sialyltransferase 1 encoded by the ST6GAL1 gene is a type-II membrane protein localized in the trans-Golgi network and catalyzes 2,6-sialylation of Gal beta 1,4‑GlcNAc structures on N-glycans (2). The enzyme is involved in the generation of the cell-surface carbohydrate determinants and differentiation antigens HB‑6, CD75, and CD76 (3). ST6GAL1 is highly expressed in the liver and also expressed in most other tissues to some extent (4). ST6GAL1 deficiency causes abnormalities in B-cell immunoreactivity (5). The expression and activity of ST6GAL1 are associated with tumor metastasis in breast (6) and colon (7) cancers. The majority of ST6GAL1 in the liver is cleaved and secreted into the serum (8) and may be used as a biomarker for hepatitis diseases (9).
