Allgemeine Beschreibung

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.

Anwendung

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.
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.

Angaben zur Herstellung

Sigma dextrans are derived from Leuconostoc mesenteroides.

Improving revascularization is one of the major measures in fracture treatment. Moderate local inflammation triggers angiogenesis, whereas systemic inflammation hampers angiogenesis. Previous studies showed that Akkermansia muciniphila, a gut probiotic, ameliorates systemic inflammation by tightening the intestinal barrier. In this
