一般描述

葡聚糖硫酸钠是α-1,6-D-吡喃葡萄糖的天然聚合物。它是一种亲水性、可生物降解和生物相容性的聚阴离子聚合物。这种高度分枝的多糖具有1,6和1,4糖苷键，每个糖基单位由2.3个硫酸盐基组成。

应用

来自明串珠菌属的右旋糖酐硫酸钠已用于：
  • 评价硫酸盐聚糖参与重组人前顶蛋白/顶蛋白与透明带（ZP）糖蛋白相互作用
  • 将胚胎第5天的小鸡胚胎注射入玻璃体腔，以评估眼睛大小，并研究其对视网膜细胞增殖的影响
  • 检测TNF-刺激基因6（TSG-6）与固定化透明质酸（HA）结合的结构特异性

生化/生理作用

硫酸右旋糖酐可能具有抗凝血和抗病毒的特性。它还有助于降低胆固醇水平。在医疗领域广泛用作血浆体积膨胀剂和纤溶剂。硫酸右旋糖酐也可用作壳聚糖的交联剂。
