Product Details

Dextran CAS#9004-54-0

Dextran, a glucose polymer composed predominantly of ol-1,6-glucopyranosidic linkages, is produced from sucrose by Leuconostoc mesenteroides and related organisms and from dextrins by other bacteria.
Dextran is used in a bead form to aid in bioreactor applications, some size-exclusion chromatography matrices and in osmotic stress technique study involved in biological molecules. It can be used as a stabilizing coating to protect metal nanoparticles from oxidation.
Dextrans are long-chain glucose polysaccharides of various relative molecular masses. Dextran 70 (relative molecular mass 70 000) is retained in the intravascular space where, like albumin, it contributes to the colloid oncotic pressure of plasma. Unlike albumin, dextran 70, when given in large amounts, prevents platelet aggregation and facilitates fibrinolysis.

Product Application of Dextran CAS#9004-54-0

Dextran is a polysaccharide with water-binding properties. It is also used to control product viscosity. Some studies indicate a capacity to enhance the anti-aging activity of formulations containing weak acids, as well as to reduce possible skin irritation arising from such acids.
