| 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: | Treatment with dextran sulfate sodium triggers development of colitis in mice and rats by binding to medium-chain-length fatty acids present in the colon and inducing inflammation. |
| 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. |
