|Description||Apramycin is an aminoglycoside 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 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. 
|In vivo||Apramycin (225 mg/L) totally suppresses mortality and significantly reduces Salmonella excretion in comparison with non-treated chicks. |
|In vitro||Water||100 mg/mL (156.82 mM)|
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
