琼脂糖Agarose，缩写为AG，是琼脂中不带电荷的中性组成成份，也译为琼胶素或琼胶糖。琼胶糖化学结构由β-D-吡喃半乳糖（1-4）连接3,6-脱水α-L-吡喃半乳糖基单位构成. 把琼脂糖，即几乎不含硫酸根的主要成分为多糖的琼脂，溶于热水，冷却制成的凝胶。制成的小颗粒用于凝胶过滤。适于用sephadex不能分级分离的大分子的凝胶过滤，若使用5%以下浓度的凝胶，也能够分级分离细胞颗粒、病毒等。利用其吸附性小的特点，有时用它代替琼脂、以作为免疫电泳或凝胶内沉降反应的支持物。
产品作用：
DNA、脂蛋白和免疫电泳用；生化研究免疫扩散等的底物。琼脂糖是线性的多聚物，基本结构是1,3连结的β-D-半乳呋糖和1,4连结的3,6-脱水α-L-半乳呋喃糖。琼脂果胶是由许多更小的分子组成的异质混合物。琼脂糖在水中一般加热到90℃以上溶解，温度下降到35-40℃时形成良好的半固体状的凝胶，这是它具有多种用途的主要特征和基础。琼脂糖凝胶性能通常凝胶强度标志。强度越高，凝胶性能越好。
外观：白色或微黄色粉末
特性：总杂质：≤1.0% 灰分 ≤10% 水分

琼脂糖
琼脂（Agar），又名琼胶、菜燕、冻粉，是一类从石花菜及其它红藻类（Rhodophyceae）植物提取出来的藻胶（phycocottoid），在我国及日本已有三百多年（1658年）的历史。琼脂糖Agarose，缩写为AG，是琼脂中不带电荷的中性组成成份，也译为琼胶素或琼胶糖。琼胶糖化学结构由β-D-吡喃半乳糖(1-4)连接3,6-脱水α-L-吡喃半乳糖基单位构成.
用途:琼脂、琼脂糖因为有特殊的胶凝性质，尤其有显著的稳固性、滞度和滞后性，并且易吸收水分，有特殊的稳定效应；已经广泛使用于食用、医药、化工、纺织、国防等领域，据不完全统计，琼脂、琼脂糖的用途已有1000多种，被国际上称为“新奇的东亚产品”。在食品工业中可用于生产：水晶软糖、定型软糖、水产品、肉类罐头、果汁饮料、果肉饮料、米酒饮料、乳品饮料、精品、乳品蛋糕。
近年来由于其良好的生物相容性又广泛用于生物分离介质的生产.
