General description【一般描述】
Dextrans are polysaccharides with molecular weights ≥1,000 Dalton, with a linear backbone of α-linked D-glucopyranosyl repeating units. Dextrans are found as bacterial extracellular polysaccharides. They are synthesized from sucrose by Leuconostoc mesenteroides and Lactobacillus brevis. Bacteria employ dextran in biofilm formation or as a protective coating to evade host phagocytes in the case of pathogenic bacteria.
Dextran from Leuconostoc mesenteroides (Mw: 670,000) may be used as an analytical standard to calibrate the column for gel permeation chromatography (GPC).
Application【应用】
将右旋糖酐用作长的亲水性间隔臂提高了作用于大分子的固定化蛋白质的性能。
