| 产品介绍 |
Dextran sulfate can interact and bind to lipids making it useful in protein isolation techniques to remove contaminating lipid molecules Dextran 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.? Applications Dextran sulfate 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 perm selectivity of membranes Dextran sulfate can interact and bind to lipids making it useful in protein isolation techniques to remove contaminating lipid molecules Dextran sulfate is supplied as a white powder which dissolves freely in water or salt solutions giving a clear solution.
