Q-葡聚糖是葡聚糖的一种阳离子衍生物。这些衍生物不同于DEAE-葡聚糖,因为它们只包含季胺基。与DEAE-葡聚糖不同,Q-葡聚糖将在很宽的pH范围内(pH 4-10)充电。Q-葡聚糖的净电荷也比相应的DEAE-葡聚糖强得多。检查所有批次的分子量、取代度和干燥损失。阿拉丁从4kDa到150kDa生产Q-葡聚糖。Q-葡聚糖以白色粉末形式提供。Q-葡聚糖是通过葡聚糖部分与2,3-环氧丙基三甲基氯化铵反应合成的。氮含量约为2%,相当于每四个葡萄糖单元一个季铵基。聚阳离子产品在细胞系统中表现出多种作用,并作为疫苗的佐剂。与相应的DEAE-葡聚糖相比,Q-葡聚糖具有更强的净电荷,因此,在这种效应很重要的系统中,会增强响应。

Product Describtion:
Q-dextran is a polycationic derivative of dextran. These derivatives are distinct from DEAE-dextrans in that they only contain quaternary amine groups. Unlike DEAE-dextrans, Q-dextrans will be charged over a wide range of pH (pH 4-10). Q-dextrans will also have a much stronger net charge than corresponding DEAE-dextrans. All batches are checked for molecular weight, degree of substitution and loss on drying. Aladdin produce Q-dextran from 4 kDa to 150 kDa. Q-dextrans are supplied as a white powder.Q-dextrans are synthesised by reacting dextran fractions with 2,3-epoxypropyltrimethylammonium chloride. The nitrogen content is approximately 2% which corresponds to one quaternary ammonium group for every four glucose units.Polycationic products exhibit a wide variety of effects in cellular systems and are of interest as adjuvants in vaccines. Q-dextran has a much stronger net charge than corresponding DEAE-dextrans and will thus give enhanced responses in systems where this effect is important.
