Protocol

Animal experiment:

Hygromycin B is dissolved in sterile water. The mice C57BL/6J-TgN(pPWL512hyg)1Ems carrying hygR are treated with a single dose of hygromycin B i.p. at doses that starts at 2.7 mg/kg and increases by 50% for each consecutive dose. Control wild-type C57BL/6J mice are treated with the same volume of sterile saline. Total volume injected is 0.5 mL. The health status and body weights of animals are monitored daily for 10 consecutive days[4].

Background

Hygromycin B is a selective antibiotic.

Antibiotics are a type of antimicrobial used in the treatment and prevention of bacterial infection.

Hygromycin B is an antibiotic that is effective on most bacteria, fungi and higher eukaryotes. Hygromycin B has a single binding site within the 30S subunit, which is in consistent with its monophasic effect. The binding site is located in the major groove of the helix with a highly sequence-specific way. Hygromycin B inhibits protein synthesis by inhibiting the translocation step of elongation and causing mistranslation of mRNA in the 70S ribosome [1]. Hygromycin B selectively inhibited activity of the ribosomal ATPase (RbbA) on 70S ribosomes and releases RbbA from 70S ribosomes at physiological concentrations. RbbA enhances the reactivity of A889 and G890 of the 16S rRNA switch helix region. Also, Hygromycin B protects G1494 and A1408 in the decoding region.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
