Application

G418 disulfate salt is an aminoglycoside antibiotic similar in structure to gentamicin used for selection and maintenance of prokaryotic and eukaryotic cells transfected with a iNOS promoter construct and neomycin resistance gene†. Optimal concentrations for selection and maintenance vary by cell lines. Bacteria and algae require 5 μg/mL or less while animal cells may require 300-500 μg/mL.

Biochem/physiol Actions

G-418 inhibits protein synthesis at the early stages of elongation, post-initiation, at the initiation stage of translation as well as just before the initiation stage of translation.

Caution

The product is stable for two years when stored at 2-8°C. Stock solutions are stable at 37°C for 8 days.
