Background | Dextran is functionalized or derivatized with amine groups. Amine groups are conjugated to DE through an amide bond. Purity: >95% powder. Amine functionalized dextrans are premier reactive dextran conjugates that can be used to react with other chemical groups. These functional dextrans were purified by size chromatography to remove non-conjugated molecules and ensure adequate applications both in-vitro and in-vivo. Dextrans are naturally synthesized polysaccharides with good water solubility, low toxicity and varied molecular weights. Dextrans modified with dyes and other biomolecules have been successfully used as long-term tracers for live cells. |
