葡聚糖-氨基外观呈白色絮状，不同的分子量也会影响葡聚糖的外观，氨基取代度为20%：例如采用20000分子量的葡聚糖，对其进行氨基化修饰，取代度为20%，即1 mol本品含117个葡萄糖单元，其中有23个葡萄糖单元被氨基化。Dextran葡聚糖（右旋糖酐Dextran）,是一类具支链葡萄糖高聚物，他不带电荷，呈电中性，易溶于水，葡聚糖跟PEG一样具有良好的生物相容性，毒性较低适用于动物体内，葡聚糖还是一种生物可降解高分子聚合物，它可降解为低分子的糖。
葡聚糖可以连接不同的活化基团如：NH2/MAL/COOH等，还可以提供一些荧光标记的葡聚糖，如：FITC/Rhodamine等。
氨基葡聚糖(glycosaminoglycan) 俗称黏多糖(mucopolysacharide )。它是含氨多糖，由重复的二糖单位聚合而成不分支的长链，二糖单元中，有一个糖残基必定是氨基己糖，即N-乙酰葡糖胺或N -乙酰半乳糖胺，故名氨基葡聚糖。
The appearance of dextran amino group is white flocculent, and different molecular weights will also affect the appearance of dextran. The degree of amino substitution is 20%. For example, dextran with 20000 molecular weight is used for amino modification, and the degree of substitution is 20%. That is, 1 mol of this product contains 117 glucose units, of which 23 glucose units are amino. Dextran dextran (dextran dextran) is a kind of high polymer with branched chain glucose. It is non charged, electrically neutral and easily soluble in water. Dextran has good biocompatibility with PEG and low toxicity. It is suitable for animals. Dextran is also a biodegradable high molecular polymer, which can be degraded into low molecular sugar.
Dextran can connect different activating groups, such as NH2 / mal / COOH, and can also provide some fluorescently labeled dextran, such as FITC / rhodamine.
Glycosaminoglycan is commonly known as mucopolysaccharide. It is an ammonia containing polysaccharide, which is a long unbranched chain formed by polymerization of repeated disaccharide units. In the disaccharide unit, one sugar residue must be aminohexose, i.e. N-acetylglucosamine or N-acetylgalactosamine, so it is called aminodextran.
