Blue dextrans are synthesised from controlled dextran fractions by reacting with Cibacron blue F3GA. After purification from non-bound dye, products are controlled for molecular weight, solubility, degree of substitution, free dye and loss on drying. TdB Labs offer blue dextran in a wide variety of molecular weights, ranging from 5 kDa to 2000 kDa.

蓝色葡聚糖是通过与 Cibacron blue F3GA 反应从受控的葡聚糖级分合成的。 从非结合染料中纯化后,对产品的分子量、溶解度、取代度、游离染料和干燥失重进行控制。 TdB Labs 提供各种分子量的蓝色葡聚糖,范围从 5 kDa 到 2000 kDa。

Structure
Dextran is a polysaccharide derived from the bacterium Leuconostoc mesenteroides B512F; and consists of an α-D-(1 – 6) linear glucan with a low content (ca. 5%) of side chains linked to 3-carbon of glucose. The dextran is then labelled with Cibacron blue F3GA.

结构
葡聚糖是一种源自肠系膜明串珠菌 B512F 的多糖; 由 α-D-(1 – 6) 线性葡聚糖组成,侧链含量低(约 5%),与葡萄糖的 3-碳相连。 然后用 Cibacron blue F3GA 标记葡聚糖。

Storage and stability
Blue dextrans are stable for more than 6 years when stored dry in well-sealed containers at ambient temperature

储存和稳定性
蓝色葡聚糖在环境温度下干燥储存在密封良好的容器中时可稳定保存 6 年以上

Solubility
Blue dextran dissolves freely in water.

溶解度
蓝色葡聚糖在水中自由溶解。
