|Description||Tilmicosin (EL 870) is a macrolide antibiotic.|
Tilmicosin inhibits growth of Pasteurella multocida, Pasteurella haemolytica, Mycoplasma hyopneumoniae, Actinobacillus pleuropneumoniae, Streptococcus suis, Actinomyces pyogenes and certain other bacteria at levels of 6.25 μg/mL or less. In general, the MICs for Gram-negative enteric bacteria have been greater than 50 μg/mL.  Tilmicosin causes decreases in cardiac SOD and GPX activities. 
|In vivo||After a subcutaneous injection, tilmicosin is eliminated more slowly from serum and milk, with t1/2 beta S of 29.3 and 41.4 hours, respectively. The apparent volume of distribution of tilmicosin is more than 1 L/kg. The peak serum tilmicosin concentration is 1.56 μg/mL. 6.39 hours after a subcutaneous injection of 10 mg/kg. Tilmicosin is extensively secreted into milk, reaching a maximum concentration of 11.6 μg/mL and having a large AUCmilk/AUCserum ratio of approximately 12:1. Tilmicosin is detectable in milk for 11 days after a single subcutaneous dose.|
|In vitro||DMSO||100 mg/mL (115.05 mM)|
|Water||8 mg/mL (9.2 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.

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.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × 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 SDS / 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 SDS / 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.
