CM葡聚糖由被羧甲基取代基取代的葡聚糖主链组成,赋予产物多阴离子性质。检查所有批次的分子量、取代度和干燥损失。阿拉丁生产4kDa至150kDa的CM葡聚糖。CM葡聚糖作为白色粉末提供。CM葡聚糖是通过将选定的葡聚糖级分与活化的羧甲基衍生物在碱中反应制备的。这导致沿葡聚糖链引入O-羧甲基。羧基含量约为5%,相当于每5个葡萄糖单元约1个CM基团。如果需要,可以实现更高的取代度CM葡聚糖可以用作敏感生物聚合物的稳定剂、配方中的无毒成分、通过羧基反应结合阳离子(无机和有机)的试剂等。

Product Describtion:
CM-dextran consists of a dextran backbone substituted with carboxymethyl substituents imparting a polyanionic character to the product. All batches are checked for molecular weight, degree of substitution and loss on drying. Aladdin produce CM-dextrans from 4 kDa to 150 kDa. CM-dextran is supplied as a white powder.CM-dextrans are manufactured by reacting selected dextran fractions with an activated carboxymethyl derivative in alkali. This leads to the introduction of O-carboxymethyl groups along the dextran chain. The carboxyl content is approximately 5% which is equivalent to about one CM group for every 5 five glucose units. Higher degrees of substitution may be achieved if requiredCM-dextran can be used as stabilisers for sensitive biopolymers, as non-toxic ingredients in formulations, as reagents for binding cations (inorganic and organic) via carboxyl reactions and more.,可以实现更高的取代度CM葡聚糖可以用作敏感生物聚合物的稳定剂、配方中的无毒成分、通过羧基反应结合阳离子(无机和有机)的试剂等。
