Dextran from Leuconostoc mesenteroides CAS No.: 9004-54-0 Dextran is a mixture of polysaccharides, a complex branched glucan. It is a glucose polymer where the linkage between glucose units are almost entirely of the α-1,6-glucan type. Dextran is a white or almost white lyophilized powder. It is soluble in water, slightly soluble in ethanol. Dextran is manufactured by hydrolysis and fractionation of polysaccharides produced by fermentation of sucrose using certain strains of Leuconostoc mesenteroides.  Dextran 5 with average molecular weight (MW) 4,000-6,000 Dextran 10 with average molecular weight (MW) 9,000-11,000 Dextran 20 with average molecular weight (MW) 16,000-24,000 Dextran 40 with average molecular weight (MW) 32,000-42,000 Dextran 60 with average molecular weight (MW) 54,000-66,000 Dextran 70 with average molecular weight (MW) 64,000-76,000 Jiagen supplies quality dextran of various specifications and average molecular weights with great pricing. For more information or to place an order, please send us an email to sales@jiagen.com and a representative will contact you within 24 hours.  References: 1.
