Low sulfated Dextran sulfates - for research and development
Dextran sulfates are produced by sulphation of selected dextran fractions. We now supply two series of dextran sulfates; one series with high levels of sulfation (16-20% sulfur) and another series with lower sulfation (8-13% sulfur).
The products are designated by the approximate molecular weights of the final products. Thus, for example, the product designated Dextran sulphate 5LS has a molecular weight of approx. 5000. The actual molecular weight is determined by GPC. This value is supplied with the COA.
The same dextran fraction is used to make the high and the low sulfated products but this results in somewhat lower mean molecular weight values for the lower sulfated products.
Specifications for each product are available on request.
Dextran sulfates act as potent polyanions and offer many interesting pharmacological and biophysical properties. Some examples of the areas of application are given below:
- cosmetics formulations
- stabilisation of sensitive biopolymers during processing or formulation
- enzyme activation or inhibition
- anti-viral preparations
- acceleration of hydridisation
