Description

• General description: Chemical structure: aminoglycoside
• Application: 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.
• Biochem/physiol Actions: Mode of action: The product acts by inhibiting protein synthesis by inducing the misreading of the m-RNA template in the prokaryote, with the potency to inhibit translation. Antimicrobial Spectrum: Hygromycin B acts against bacteria, fungi and higher eukaryotic cells.
• Caution: 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.
• Preparation Note: This product is a solution that is =60% (HPAE), 45-60 mg/mL in H2O, and γ-irradiated .
