Low sulfate dextran

Low sulfate dextran

CAS Number: 9011-18-1

Dextran sulfates are produced by sulfation of selected dextran fractions. TdB Labs produce low sulfated dextran sulfates from 5 kDa to 500 kDa.
The dextran sulfate is supplied as the sodium salt and is stabilised by a small addition of phosphate salts. A certificate of analysis is supplied with each batch. The molecular weight range, sulfur content, moisture etc. are carefully controlled.

Structure
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. Dextran sulfate is a sulfated derivative of selected dextran fraction. The sulfate content of our low sulfated dextran sulfates lies between 8 to 13 %.

Storage and Storage and stability
Dextran sulfate is stable for more than 6 years when stored dry in well-sealed containers at ambient temperature

Solubility
Dextran sulfate is readily soluble in water.
