Carbohydrate Sulfotransferase 3/CHST3 antibody in Human Pancreas by Immunohistochemistry (IHC-P).

Carbohydrate Sulfotransferase 3/CHST3 in Human Pancreas.

Carbohydrate Sulfotransferase 3/CHST3 was detected in immersion fixed paraffin-embedded sections of human pancreas using Rat Anti-Human Carbohydrate Sulfotransferase 3/CHST3 Monoclonal Antibody (Catalog # MAB7450) at 15 µg/mL overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm of endocrine cells. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Background: Carbohydrate Sulfotransferase 3/CHST3

The human CHST family is comprised of 14 enzymes. All members of this family are Golgi-localized type II membrane proteins. Only the luminal and enzymatic domain is expressed in each of our recombinant CHST proteins. These enzymes transfer sulfate (i.e., sulfonate) onto the 6-O or 4-O positions of GalNAc, Gal and GlcNAc residues on glycoproteins, proteoglycans and glycolipids (1). This sulfation often creates specific epitopes that can be recognized by extracellular matrix proteins, cell surface receptors and viruses (2). CHST3, also known as chondroitin 6-O-sulfotransferase, transfers sulfate to position 6 of GalNAc residues on chondroitin sulfate (3). Chondroitin sulfate constitutes the predominant proteoglycan present in cartilage and is distributed on the surfaces of many cells and extracellular matrices. Loss of CHST3 function in human results in severe chondrodysplasia (4). CHST3 can also sulfate Gal residues of keratan sulfate and Gal residues in sialyl N-acetyllactosamine (sialyl LacNAc) oligosaccharides (5). The enzymatic activity of the recombinant human CHST3 was measured using a phosphatase-coupled sulfotransferease assay (6).
