描述

一般說明

Chemical structure: aminoglycoside

應用

Hygromycin B is an aminoglycoside antibiotic isolated from Streptomyces hygroscopicus. It has been used to study protein synthesis at the level of the 70S ribosome translocation and mRNA template misreading, as an antiviral agent by selectively penetrating cells rendered permeable by virus infection and inhibiting translation, and as a selection agent for hygromycin resistance gene transformed cells. It is recommended for use as a selection agent at 100-800 μg/mL, specifically at 100 μg/mL for prokaryotes, 200 μg/mL for lower eukaryotes and 150-400 μg/mL for higher eukaryotes..

生化／生理作用

作用机制：本品通过诱导原核生物中m-RNA模板的误读，抑制蛋白质合成，具有抑制翻译的作用。

抗菌谱：潮霉素B对细菌、真菌和高等真核细胞有抑制作用。

注意

Hygromycin B products should be stored as supplied at 2-8°C, and the dry solid is stable for at least 5 years if stored at 2-8°C. It is stable at 37°C for 30 days.

準備報告

This product is purified by ion exchange chromatography. Hygromycin B is soluble in water at concentrations >50 mg/mL, and also soluble in methanol or ethanol. Solutions should be sterilized by filtration, not by autoclaving. Additionally, Hygromycin B solutions have been reported to lose activity on freezing, and since they are stable refrigerated, freezing should be avoided.
