Descripción

General description

Dextran is a polymer of anhydroglucose. It is composed of approximately 95% alpha-D-(166) linkages. The remaining (163) linkages account for the branching of dextran.

Application

Dextran sulfate is routinely used for the selective precipitation of lipoproteins, probe hybridization membrane-immobilized DNA, the release of DNA from DNA-histone complexes, and the inhibition of RNA binding to ribosomes.

Biochem/physiol Actions

Dextran sulfate can interact and bind to lipids making it useful in protein isolation techniques to remove contaminating lipid molecules.

Preparation Note

Sigma dextrans are derived from Leuconostoc mesenteroides.
