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.

Dextran sulfate increases binding of epithelial cells and lymphocytes to extracellular matrix proteins including fibronectin and laminin. In addition, dextran sulfate altered expreβion of cell surface receptors integrins.

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.

Preparation Note

Sigma dextrans are derived from Leuconostoc mesenteroides.
