Mouse Carbohydrate Sulfotransferase 4/CHST4 Antibody Summary

Species Reactivity
Detects mouse Carbohydrate Sulfotransferase 4/CHST4 in direct ELISAs and Western blots. In direct ELISAs and Western blots, approximately 40% cross‑reactivity with recombinant human (rh) CHST4 is observed and less than 5% cross‑reactivity with recombinant mouse CHST5 and rhCHST6 is observed.
Polyclonal Sheep IgG
Antigen Affinity-purified
Chinese hamster ovary cell line CHO-derived recombinant mouse Carbohydrate Sulfotransferase 4/CHST4
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied either lyophilized or as a 0.2 µm filtered solution in PBS.

See below
Measured by its ability to neutralize Recombinant Mouse Carbohydrate Sulfotransferase 4/CHST4 (8.33 µg/mL, Catalog # 5547-ST) transfer from the sulfate donor Adenosine 3'-phosphate 5'-phosphosulfate (PAPS, 33 μM) to beta ‑D‑GlcNAc-1→6)-alpha -D-Man→OMe (XXX nM). The Neutralization Dose (ND50) is typically 60 µg/mL.

Detection of Mouse Carbohydrate Sulfotransferase 4/ CHST4 by Western Blot. Western blot shows lysates of bEnd.3 mouse endothelioma cell line. PVDF Membrane was probed with 1 µg/mL of Sheep Anti-Mouse Carbohydrate Sulfotransferase 4/CHST4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5547) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for Carbohydrate Sulfotransferase 4/CHST4 at approximately 60 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: Carbohydrate Sulfotransferase 4/CHST4

The mouse CHST family is comprised of 13 enzymes. All members of this family are Golgi-localized type II membrane proteins (1). Only the luminal and enzymatic domain is expressed in each of the 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 (2). This sulfation often creates specific epitopes that can be recognized by extracellular matrix proteins, cell surface receptors and viruses (3). Human CHST4, also known as high endothelial cell N-acetylglucosamine 6-O-sulfotransferase (HEC-GlcNAc6ST) or L‑selectin ligand sulfotransferase (LSST), catalyzes the transfer of sulfate to position 6 of non-reducing GlcNAc residues within mucin-associated glycans that ultimately serve as L‑selectin ligands (4). It has a catalytic preference for core 2-branched mucin-type O‑glycans, but also has activity toward core 3 type of O‑glycans (5). Mouse CHST4 shares 72% amino acid sequence identity with the human ortholog.
