|Description||Geneticin (G418 Sulfate), an aminoglycoside antibiotic, is an elongation inhibitor of 80 S ribosomes that blocks polypeptide synthesis by inhibiting the elongation step in both prokaryotic and eukaryotic cells.|
G418 is an inhibitor of many pro- and eukaryotes at concentrations from 1-300 microgram/ml. Resistance to G418 conferring by the neo gene from Tn5 encoding an aminoglycoside 3'-phosphotransferase, APT 3' II is commonly used in laboratory research to select genetically engineered cells.  In general for bacteria and algae concentrations of 5 mg/L or less are used, for mammalian cells concentrations of approximately 400 mg/L are used for selection and 200 mg/L for maintenance. Resistant clones selection could require from 1 to up to 3 weeks. 
|In vivo||Doses of G418 of between 40 and 80 mg/kg for three consecutive days are sufficient to eliminate all nontransfected T. brucei brucei parasites from infected mice. |
|In vitro||Water||100 mg/mL warmed (144.36 mM)|
|In vivo||Saline||30 mg/mL|
* 1 mg/ml means slightly soluble or insoluble.
* 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.
