Application

Heparan sulfate sodium salt from bovine kidney has been used:
  • to investigate its effect on proliferation of B cells
  • to monitor its role on eye development in E5 embryonic cells
  • to study its binding with exosome fibronectin in human trabecular meshwork cells using dot blot

Biochem/physiol Actions

Constituent of membrane-associated proteoglycans suggested to contribute to cell-cell adhesion
Heparan sulphate (HS), a ubiquitous glycosaminoglycan, is a polymer of D-glucuronic acid or L-iduronic acid and D-glucosamine (GlcA) sugars. It is synthesized in the cis-Golgi as heparan. In Golgi, final heparan sulphate is synthesized in by the action of enzymes N- and O-HS-sulphotransferases and HS epimerase. The mature HS has 50 to 200 disaccharide units. It is part of the extracellular matrix (ECM) and plays a key role in the oncogenic pathway. Deregulation of heparin sulfate metabolism is implicated in cancer progression. HS is associated with the onset of infectious diseases and inflammatory conditions. HS interaction with Aβ fibrils contributes to the pathophysiology of Alzheimer′s disease.Heparan sulphate is a constituent of membrane-associated proteoglycans suggested to contribute to cell-cell adhesion.

Questions

1–3 of 3 Questions  
  1. Was the anticoagulant activity of this product determined? Is degree of contamination with heparin known?

    1 answer
    1. The anticoagulant activity for H7640 is not determined during quality control testing. The testing that is performed is limited to appearance, solubility, Infrared Spectrum, Nitrogen and Sulfur only. There are heparin sodium salt products that do test for anticoagulant activity, Among the heparin sodium salt products that test for anticoagulant activity are H3393, H3149, H4784, H5515 and 2106.

    1. Response from Merck KGaA:

      Thank you for reaching out and sharing your review with us. Heparan Sulfate is a polysaccharide with a variable molecular weight. We do not provide a quantitative purity value for this product, however it is used as a substrate in testing of our Heparinase III product, H8891. We report the sulfur content on the lot-specific Certificate of Analysis. The molecular weight range of this product is 10 - 14 dDa. For further discussion, we welcome you to contact our Technical Service team by visiting https://www.sigmaaldrich.com/support/customer-support and submitting a Product Technical Inquiry. We hope to hear from you soon!
