General description

右旋糖酐是分子量为≥1,000道尔顿的多糖，具有由α-连接的D-葡吡喃糖基重复单元组成线性骨架。右旋糖酐是某些细菌产生的一种胞外多糖。由肠膜明串珠菌 (Leuconostoc mesenteroides) 和短乳杆菌 (Lactobacillus brevis) 通过蔗糖合成。细菌合成右旋糖酐用于生物被膜形成，致病菌则将其作为保护性包被以便入侵宿主的吞噬细胞。肠膜明串珠菌
右旋糖酐（Mw：5000）可作为分析标准品，用于校准凝胶渗透色谱 (GPC) 的色谱柱。

Application

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。
