應用

右旋糖酐在许多应用中用作血小板聚集剂、血浆增容剂、渗透压调节剂、稳定剂、器官分离介质、基质成分、共聚物、微载体、结合剂、粘度调节剂、抗血栓药、润滑剂和物理结构成分。右旋糖酐可用作长的亲水性间隔臂，以改善结合/结合蛋白的性能（自由活动）。右旋糖酐可衍生化用于生物传感器系统。右旋糖酐 150 可用于研究铁转运至细胞、细胞膜通透性增加和红细胞聚集。
将右旋糖酐用作长的亲水性间隔臂提高了作用于大分子的固定化蛋白质的性能。

準備報告

除了最高分子量的葡聚糖D5501（分子量范围= 500万至4,000万），其他葡聚糖都具有非常好的水溶性。 Sigma测试显示，葡聚糖在水中的溶解浓度通常超过30mg/ml。葡聚糖也易溶于DMSO、甲酰胺、乙二醇和甘油。中性-水性葡聚糖溶液可通过在110-115oC下高压灭菌30至45分钟进行灭菌。葡聚糖在高温下可以被强酸水解。葡聚糖的末端还原性端基可在碱性溶液中氧化。

Dextran

Dextran is a polymer of anhydroglucose. It is composed of approximately 95% alpha-D-(1-6) linkages. The remaining a(1-3) linkages account for the branching of dextran. Conflicting data on the branch lengths implies that the average branch length is less than three glucose units. However, other methods indicate branches of greater than 50 glucose units exist.
