硫酸葡聚糖是由特定分子量的葡聚糖硫酸化反应制得的。TdB生产的低取代度硫酸葡聚糖分子量从5 kDa到500 kDa。

硫酸葡聚糖是以钠盐形式呈现，并加入少量磷酸盐作为稳定剂。 每个批次的产品都提供质检报告COA。严格仔细控制分子量程，含硫量，湿度等指标。

葡聚糖是一种多糖，来源于肠系膜明串珠菌B512F，由α-D-(1-6)线性葡聚糖组成，侧链含量较低（约5%），与葡萄糖的碳-3位相连。硫酸葡聚糖是特定分子量的葡聚糖硫酸化得到的衍生物。低取代度硫酸葡聚糖的硫酸组分在8-13%之间。

硫酸葡聚糖（DS）可按不同平均重均分子量，不同分子量分布，不同程度的取代度，不同阳离子（例如钾替代钠）和不同硫酸化过程来生产。例如，仅凭硫酸葡聚糖70的名称无法完整识别该化合物，在评估这些化合物性能时应考虑到这一点。

硫酸葡聚糖是由选定的葡聚糖片段和硫酸化试剂（例如氯磺酸）合成而来，反应混合物经过纯化后，可以获得白色粉末状产品。

室温下，硫酸葡聚糖在干燥密闭的容器内可以保持稳定超过6年。

硫酸葡聚糖涉及广泛的应用领域和性质。举例如下

• 细胞培养用的抗凝剂
• 脂蛋白的选择性淀析
• 加速DNA杂交
• 从DNA-组蛋白复合物中释放DNA
• 抑制tRNA与核糖体的结合
• 核糖核酸酶抑制剂
• 抗病毒性
• 用于化妆品的抗感染和透水保湿
• 分离微生物和大分子
• 疫苗佐剂
• 膜选择性渗透研究
