Taking the 1 mL working solution as an example, add 30 mg of this product to 1 ml of physiological saline (0.9% NaCL solution), mix evenly to make it clear, The mixed solution should be used immediately for optimal results.

* <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.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

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.It is commonly used as a screening reagent for eukaryotic cells to screen transfected or transformed cells.
In vitro	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. ^[1] 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. ^[2]
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. ^[3]
