General description

Dextrans are polysaccharides with molecular weights ā‰„1,000 Dalton, with a linear backbone of Ī±-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

El uso de dextranos como brazos espaciadores largos e hidrĆ³filos mejora el rendimiento de las proteĆ­nas inmovilizadas que actĆŗan sobre las macromolĆ©culas.
