产品说明

一般描�?/p>

Dextrans are polysaccharides with molecular weights ��1,000 Dalton, with a linear backbone of ��-linked D -glucopyranosyl repeating units. Dextrans are found as bacterial extracellular polysaccharides. They are synthesized from sucrose byLeuconostoc mesenteroidesandLactobacillus brevis. Bacteria employ dextran in biofilm formation or as a protective coating to evade host phagocytes in the case of pathogenic bacteria.
Dextran fromLeuconostoc mesenteroides(Mw: 410,000), may be used as an analytical standard to calibrate the column for gel permeation chromatography (GPC).
