Dextran sulfate can interact and bind to lipids making it useful in protein isolation techniques to remove contaminating lipid moleculesDextran sulfate is supplied as a white powder which dissolves freely in water or salt solutions giving a clear solution.Dextran sulfates may be produced with a wide range of molecular weights and degrees of sulfation. Each of the products within this range is supplied with sulphur contents of 16-20%. Dextran sulfates act as potent polyanions and offer many interesting pharmacological and biophysical properties. Dextran sulfates are produced by sulfating selected dextran fractions. 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. 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.?ApplicationsDextran sulfate have a wide range of applications areas and properties. Some examples are:Anti-coagulation agent in cell mediaSelective precipitation of lipoproteinsAcceleration of DNA hybridisation.Releasing DNA from DNA-histones complexesInhibition tRNA-binding to ribosomesInhibition of ribonucleasesAnti-viral propertiesUsed in cosmetics for anti-inflammation properties and osmotic retention of waterSeparation of microorganisms and macromoleculesAdjuvant in vaccinesStudies of perm selectivity of membranes
