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.
NOTE: we can provide Pharmaceutical grade purityon demand if you aim to use our products as Raw Matrials for the pharmaceutical formulations, medical devices or related. We fulfill requirements from the European Pharmacopoeia (EP) for production and quality for “Dextran for injection” that are in accordance with EDQM certification, including testing for microbial contamination and bacterial endotoxins, sulfated ash, heavy metals and more. Let us know prior to your order if you need PharmaGrade purity.
