一般說明

硫酸庆大霉素盐是一种广谱氨基糖苷类抗生素,衍生自紫癜性小单孢子菌。

應用

硫酸庆大霉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/mL。 硫酸庆大霉素可用于:
  • 抗生素对不同细菌培养物的有效性研究中
  • 研究神经元信号处理

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,StaphylococcusStreptococcus 的抗性。

特點和優勢

适合多种研究应用的高质量抗生素

成分

庆大霉素是Micromonospora purpurea 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。
易溶于水,几乎不溶于乙醇

儲存和穩定性

无菌溶液应储存在2-8°C条件下。溶液在室温及沸腾的pH 2-14的水性缓冲液中稳定。[2]

Plant hosts recruit and maintain a distinct root-associated microbiota based on host and bacterium traits. However, past studies disregarded microbial strain-host specificity and spatial micro-heterogeneity of the root compartment.
