應用

葡聚糖被用于许多应用，如作为血小板凝集剂、血浆增容剂、渗透压调节剂、稳定剂、器官分离介质、基质组分、共聚物、微载体、粘合剂、粘度调节剂、抗血栓形成剂、润滑剂和物理结构组分。它们可以用作长亲水间隔臂，改善缀合/结合蛋白的性能（运动自由度）。葡聚糖可以衍生化，用于生物传感器系统。
小于60,000Da的葡聚糖通常被认为是低分子量葡聚糖。 低分子量葡聚糖的粘度、聚集和渗透性质使其通常优于高分子量葡聚糖。 高分子量、水溶性葡聚糖聚合物已可用于各种生物医学应用中。葡聚糖（9,000-11,000），是一种低分子量葡聚糖，可用于研究瞬时细胞膜和血脑屏障（BBB）透化等过程。在蛋白质包装和折叠研究中，它可以用作糖类拥挤剂。
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

葡聚糖是具有很好的水溶性，最高分子量的葡聚糖D5501(分子量范围 =500万至4000万)除外。 Sigma测试葡聚糖在水中的溶解度通常超过30mg/ml。 葡聚糖也易溶于 DMSO、甲酰胺、乙二醇和甘油。 中性葡聚糖水溶液可在110-115oC下高压灭菌30至45分钟。葡聚糖在高温下可被强酸水解。葡聚糖的末端还原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.

Dextran Sulfate

Dextran sulfates are supplied as the sodium salt forms, making them soluble and stable in water. Dextran sulfate contains approximately 17% sulfur which is equivalent to approximately 2.3 sulfate groups per glucosyl residue.
