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. [1]
Preparation Note
Sigma dextrans are derived from Leuconostoc mesenteroides.
