产品说明
一般描述
Dextrans are polysaccharides with molecular weights ≥1,000 Dalton, with a linear backbone of α-linked
Dextran from Leuconostoc mesenteroides (Mw: 25,000) may be used as an analytical standard to calibrate the column for gel permeation chromatography (GPC).
Dextran is a D-glucosyl homopolysaccharide which has a-1,6 glucosidic linkages with different branches through α-1,2, α-1,3, and α-1,4 linkages correspondingly classified as group A, B and C. It can be synthesized from sucrose by cell-free filtrate.
应用
Markers-dextran with 25000 Da has been used as standard in gel chromatography analysis to determine fractional composition of protein, carbohydrate, phenolic surface active substances in base wine.
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。
