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.
Dextran sulfate 5 (DS5) is one of our most demanded products commonly used as a cell culture media additive. We produce both high and low sulfated dextran sulfate 5 kDa of premium quality. Technical and Pharma grade available.
Dextran sulfate 10 (DS10) is increasingly used in cosmetics and other application areas, and we produce both bulk and smaller amounts of high and low sulfated dextran sulfate 10 kDa of premium quality. Technical and Pharma grade available.
