- Highly cited
G418 is a gentamycin-class aminoglycoside antibiotic with cytotoxic properties in both prokaryotic and eukaryotic cells. In a cell-free assay, G418 inhibits 80S ribosome and protein elongation during translation. In cells, G418 induces apoptosis and is widely employed in the selection of eukaryotic expression vectors containing the neomycin resistance gene neoR, in combination with either APH(2'') or APH(3').

| Technical Info/Product Notes: | The effective killing concentration of this antibiotic will vary as to the cell type, media, growth conditions, and the cells metabolic rate and position in the cell cycle. Effective concentrations have been reported from 100µg/ml up to 5mg/ml or greater. When using G418 in a new cell system, a full dose curve is suggested and with each new lot of G418, several points on that curve should be retested, as the potency determined in a standard B. subtilis assay may not exactly correlate to your system. |
