说明

一般說明

Chemical structure: aminoglycoside

應用

Gentamicin sulfate, a broad-spectrum antibiotic, used as a selection agent (gentamicin-resistance gene) in cell culture and molecular biology applications. This product is recommended for use at 50 mg/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。

成分

Gentamicin is an aminoglycoside complex produced by fermentation of Micromonospora purpurea or M. echinospora. It is used as the sulfate salt. There are three components, each consisting of five basic nitrogens and requiresing five equivalents of sulfuric acid per mole of gentamicin base.

注意

Sterile solutions should be stored at 2-8°C. Solutions have also been shown to be stable at room temperature and in boiling aqueous buffers of pH 2-14².
