应用

硫酸庆大霉素，是一种广谱抗生素，在细胞培养和分子生物实验中作为选择剂（抗庆大霉素基因）。 产品推荐使用浓度是50mg/L。

生化/生理作用

作用机制：庆大大霉素通过和30S核糖亚基结合，引起密码子误读，阻碍肽酰转移酶从供体位点转移到受体位点。庆大霉素通过它与外膜的结合来发挥它对铜绿假单胞菌的杀菌作用，它在外膜上置换天然阳离子，使膜不稳定，并在细胞表面形成孔。

抗菌谱：包括革兰氏阴性和革兰氏阳性细菌，包括对于四环素、氯霉素、卡那霉素和粘菌素，某些特定假单胞菌菌株，变形杆菌属，Staphylococcus 和 Streptococcus 的抗性。

组分

庆大霉素是Micromonospora purpurea 或M. echinospora发酵后产生的氨基糖苷复合物。 它可以用来作为硫酸盐。 每摩尔庆大霉素基础有三个成分，每一个成分包含五份碱性氮，并且需要5份硫酸。

注意

无菌溶液需要储存在2-8℃。溶液在室温下和沸腾的pH 2-14的水性缓冲液中稳定。
