一般說明

G-418是一种由小单孢菌NRRL 5326菌株产生的氨基糖苷类抗生素。它在体内体外均具有光谱的抗菌活性。它还显示出对原生动物、盲肠阿米巴虫和蠕虫的活性。它通常作为遗传霉素选择性抗生素而被人们所熟知。
化学结构:氨基糖苷类

應用

G418二硫酸盐是一种氨基糖苷类抗生素,结构与庆大霉素相似,可用于筛选和维持利用iNOS启动子构建体以及新霉素抗性基因转染的原核和真核细胞†。不同细胞系具有不同的筛选和维持最佳浓度。 细菌和藻类最多需要5 μg/mL而动物细胞则可能需要300-500 μg/mL。

生化/生理作用

G-418对于蛋白合成的抑制是在延伸的早期阶段、起始后、翻译起始阶段以及翻译将要起始的阶段之前。

注意

该产品可2-8°C稳定储存两年。储备溶液可37°C稳定储存8天。

準備報告

G418粉末可以100 mg/mL溶于水。

其他說明

保持容器密闭并置于干燥通风处。置于干燥处。
