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 (Sigma) can be used to precipitate the lipoprotein HDL from human plasma samples.
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.
Preparation Note
Sigma dextrans are derived from Leuconostoc mesenteroides.
