Dextran sulfates

Dextran sulfate is an anionic derivative of dextran produced by sulfation of selected dextran fractions. Dextran is a polysaccharide derived from the bacterium Leuconostoc mesenteroides B512F and consists of an α-D-(1 – 6) linear glucan with a low content (ca. 5%) of sidechains linked to the 3-carbon of glucose. We now supply two series of dextran sulfates; one series with high sulfate content (16-20% sulfur) and another series with lower sulfate content (8-13% sulfur).

TdB Labs produce dextran sulfates with a mean molecular weight ranging from 5 kDa to 2000 kDa.

All our dextran sulfates are manufactured by the same process which gives pure white products.

Looking for pharma grade please check Dextran sulfate Pharma grade.

High sulfate dextran

CAS Number: 9011-18-1

The degree of sulfatation of our high sulfated dextran sulfates lies between 16 to 20 %. We produce high sulfated dextran sulfates from 5 kDa to 2000 kDa.

Low sulfate dextran

CAS Number: 9011-18-1

The sulfate content of our low sulfated dextran sulfates lies between 8 to 13 %. TdB Labs produce low sulfated dextran sulfates from 5 kDa to 500 kDa.

Applications

Dextran sulfates have a wide range of applications areas and properties. Some examples are:

Anti-coagulation agent in cell media
Selective precipitation of lipoproteins
Acceleration of DNA hybridisation.
Releasing DNA from DNA-histones complexes
Inhibition tRNA-binding to ribosomes
Inhibition of ribonucleases
Anti-viral properties
Used in cosmetics for anti-inflammation properties and osmotic retention of water
Separation of microorganisms and macromolecules
Adjuvant in vaccines
Studies of permeal selectivity of membranes
