|Description||Marbofloxacin is a potent antibiotic inhibiting bacterial DNA replication.|
Marbofloxacin is a fluoroquinolone antimicrobial agent developed exclusively for veterinary use. Marbofloxacin exhibits high bactericidal activity against a broad spectrum of aerobic Gram-negative and some Gram-positive bacteria, as well as Mycoplasma spp. As the third generation fluoroquinolone, Marbofloxacin also mainly targets replication and transcription enzymes such as DNA gyrase and topoisomerase IV, which are both essential for bacterial viability. Marbofloxacin has a mycoplasmacidal effect during the exponential phase but not during the lag phase, in both the M. hyopneumoniae 116 wild-type strain and a clone isolated 4 days post-marbofloxacin treatment in vivo at the therapeutic dose.  Marbofloxacin significantly kills Leishmania promastigotes and intracellular amastigotes in a dose-dependent manner, more efficient than meglumine antimoniate and sodium stibogluconate. After treatment with Marbofloxacin, macrophages acquire resistance to infection and enhanced antileishmanial activity through the NO synthase pathway. 
|In vivo||Marbofloxacin treatment at the therapeutic dose does not eliminate M. hyopneumoniae, with 87.5 to 100% of the pigs still positive at the end of the assays, and is not effective in significantly reducing clinical signs. Nevertheless, Marbofloxacin treatment seems to decrease the lung lesion scores.  Administration of Marbofloxacin at 6 mg/kg once daily for 7 days in a Staphylococcus aureus infection in tissue cages in ponies is not effective for the elimination of S. aureus infections from secluded sites. |
|In vitro||DMSO||3 mg/mL warmed (8.27 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
1% DMSO+30% polyethylene glycol+1% Tween 80, pH 4
For best results, use promptly after mixing.
* 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 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.
