Product Description

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.
ln Vivo
Apramycin (225 mg/L) totally suppresses mortality and significantly reduces Salmonella excretion in comparison with non-treated chicks.

Solubility (In Vivo)
Solubility in Formulation 1: 100 mg/mL (156.82 mM) in PBS (add these co-solvents sequentially from left to right, and one by one), clear solution; with sonication.

Solubility in Formulation 2: PBS : 100 mg/mL (156.82 mM)

 (Please use freshly prepared in vivo formulations for optimal results.)
Preparing Stock Solutions 1 mg 5 mg 10 mg

*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.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
