| Description | G-418 disulfate (Geneticin sulfate) is an aminoglycoside antibiotic that selectively inhibits eukaryotic protein synthesis by blocking peptide chain elongation. |
| Targets&IC50 | BHK-21 cells:69 µg/mL, CHO-K1 cells:311 µg/mL, HeLa cells:483 µg/mL, 3T3 cells:213 µg/mL |
| In vitro | Continuous administration of G418 at doses ranging from 40 to 80 mg/kg for three consecutive days is sufficient to eradicate all untransfected Brucella bacterium parasites in infected mice. |
| In vivo | At concentrations ranging from 1 to 300 micrograms/ml, G418 inhibits a variety of prokaryotic and eukaryotic organisms. Typically, concentrations of 5 mg/L or lower are effective against bacteria and algae, while a concentration of 400 mg/L is used for the selection of mammalian cells, and a maintenance concentration for mammalian cells is set at 200 mg/L. |
