General description

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: 150,000) may be used as an analytical standard to calibrate the column for gel permeation chromatography (GPC).

Application

Use of dextrans as long and hydrophilic spacer arms improves the performance of immobilized proteins acting on macromolecules.
