Application Abreviews Notes
ICC/IF Use at an assay dependent concentration. PubMed: 24247246
WB Use a concentration of 1 µg/ml. Predicted molecular weight: 36 kDa. Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.


  • Function
    Sulfotransferase that utilizes 3'-phospho-5'-adenylyl sulfate (PAPS) to catalyze the transfer of a sulfo group to position 3 of glucosamine residues in heparan. Catalyzes the rate limiting step in the biosynthesis of heparan sulfate (HSact). This modification is a crucial step in the biosynthesis of anticoagulant heparan sulfate as it completes the structure of the antithrombin pentasaccharide binding site.
  • Tissue specificity
    Highly expressed in the brain and kidney and weakly expressed in the heart, lung and placenta.
  • Sequence similarities
    Belongs to the sulfotransferase 1 family.
  • Cellular localization
    Golgi apparatus lumen.

  • Anti-HS3ST1 antibody (ab91065) at 1 µg/ml (in 5% skim milk / PBS buffer) + Human fetal stomach lysate at 10 µg

    HRP conjugated anti-Rabbit IgG at 1/50000 dilution

    Predicted band size : 36 kDa

  • Cells were fixed with 4% paraformaldehyde for 15 minutes at room temperature and permeabilized with permeabilization buffer + 10% FBS in PBS for 10 minutes. Cells were incubated with ab91065 and goat anti-GM130 Golgi marker (ab1299) overnight at 4°C in the dark. Cells were washed once and stained with Alexa Fluor 647-conjugated donkey anti-rabbit IgG and Alexa Fluor 488-conjugated donkey anti-goat IgG secondary antibodies. DAPI - DNA. Dual-29 cells were used as a positive control, and the other cell samples were then evaluated at the same frequency. Overexpression of HS3st1 in Dual-29 cells resulted in a broad distribution of HS3st1. Overexpression of HS3st1 in Dual-10 cells localized HS3st1 in the Golgi. Overexpression of Golgi-targeted HS3st1 in CHO-gt31 localized HS3st1 in the Golgi.
