Apramycin (also known as Ai3-29795; Nebramycin II) is a broad spectrum and aminoglycoside class of antibiotic, which binds to the deep groove of the RNA. Apramycin consumption at farm level is most probably driving the increasing occurrence of apramycin/gentamicin cross-resistant [aac(3)-IV positive] E. coli in diseased pigs and healthy finishers at slaughter. Apramycin inhibits A. pleuropneumoniae FMV 87-682 with MIC50 of 8 mg/L. Apramycin (1/4 MIC) in the medium decreases the rate of growth of the bacterial strains tested, and causes the postantibiotic effect (PAE) up to 5 hours.

Apramycin consumption at farm level is most probably driving the increasing occurrence of apramycin/gentamicin cross-resistant [aac(3)-IV positive] E. coli in diseased pigs and healthy finishers at slaughter. Apramycin inhibits A. pleuropneumoniae FMV 87-682 with MIC50 of 8 mg/L. Apramycin (1/4 MIC) in the medium decreases the rate of growth of the bacterial strains tested, and causes the postantibiotic effect (PAE) up to 5 hours. Apramycin significantly reduces the haemolytic activity of A. pleuropneumoniae and affects the capsular material production of this isolate and of one isolate of P. multocida (type A). Apramycin induces translation errors, as assayed by incorporation of leucine, isoleucine and serine, although this effect occurs only to a limited extent, in cell-free systems from Escherichia coli programmed with poly(U). Apramycin inhibits the translocation step of protein synthesis both in vivo, in protoplasts of Bacillus megaterium, and in vitro, in cell-free systems from E. coli.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration: mg/mL;
Method for preparing DMSO stock solution: mg drug pre-dissolved in μL DMSO (stock solution 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 stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
