1 TdB多糖产品简介
TdB产品线是由荧光和非荧光多糖衍生物组成。TdB专注于葡聚糖衍生物,同时也提供其它多糖衍生物,
例如聚蔗糖、菊粉、透明质酸、海藻糖和羟乙基淀粉。产品广泛应用于生命科学领域。
荧光多糖衍生物产品,主要用于细胞和组织的渗透性和微循环研究,以及药物输送研究和作为分子级别
的标记使用。荧光产品线由21组不同分子量的荧光多糖组成,包括了FITC, TRITC, ATTO™-染料和特有
的Antonia Red™-染料标记衍生物。
非荧光多糖衍生物,包括带羧甲基(CM),二乙胺基乙基(DEAE)和季铵盐(Q)官能团的硫酸葡聚糖
和带电极性多糖。硫酸葡聚糖钠(DSS)是最受关注的产品之一,用于肠炎模式小鼠和大鼠的建模已超过
20年历史。 低分子量的硫酸葡聚糖常用于细胞培养添加物或作为稳定剂使用。蓝色葡聚糖常被用作色谱
中的空柱标记。苯基-葡聚糖则可用于制备疏水性凝胶和涂料。
硫酸葡聚糖是由特定分子量的葡聚糖经硫酸化得到的阴离子衍生物。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。TdB
提供两种不同系列的硫酸葡聚糖,高硫酸化和低硫酸化系列。硫酸葡聚糖的平均分子量范围从 5 kDa
到2000 kDa。所有硫酸葡聚糖产品都是通过相同的过程生产的,皆为纯白色产品。
高取代度硫酸葡聚糖含16-19%硫酸,分子量从5 kDa到2000 kDa。
低取代度硫酸葡聚糖含8-13%硫酸,分子量从5 kDa到500 kDa。
硫酸葡聚糖钠(DSS),用于肠炎建模。硫酸葡聚糖钠 (DSS)是实验动物肠炎建模的金标试剂。DSS是
平均分子量在40KDa,硫含量17-19 %的硫酸葡聚糖盐。早在近40年前,TdB就开始肠炎建模级DSS的
开发工作。
蓝色葡聚糖是使用Cibacron blue F3GA标记。可以生产平均分子量范围5 kDa 到2000 kDa的蓝色葡聚糖。
其它衍生物和多糖:非荧光衍生物包括羧甲基(CM),二乙胺基乙基(DEAE),赖氨酸和苯基官能
团修饰的葡聚糖和聚蔗糖。
全新的染料系列:FITC (异硫氰酸荧光素) 和Cibacron Blue 3G-A。FITC (异构体I) 是一种有广泛应用的
荧光染料,可以和多糖蛋白和其它分子共轭结合。Cibacron Blue 3G-A是一种蒽醌类染料,常用于亲
和层析色谱。

3 TdB多糖产品质量控制
纯度:所有标准品都是技术纯级。对于部分应用,例如用于医疗设备,需要更高的产品纯度。
质量:所有产品都拥有一流的质量。多糖衍生物具有高纯度和低聚合物分散性(PD), 即
重均分子量Mw与数均分子量Mn之比接近于1。 对于渗透性研究来说,这点尤为重要。
低分散性使检测结果更可靠,重复性更好。
