一般說明

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。

應用

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。

Layer-by-Layer (LbL) Assembly, A "Gentle Yet Flexible" Method Toward Functional Biomaterials

Recently, layer-by-layer (LbL) assembly has emerged as a versatile, gentle and, simple method for immobilization of functional molecules in an easily controllable thin film morphology.1,2 In this short review, we introduce recent advances in functional systems fabricated by using the mild, yet adaptable LbL technique.
