General description

Chemical structure: aminoglycoside

Packaging

250 mg in glass bottle
1, 5 g in glass bottle

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.

Caution

The product is stable for three years when stored at 2-8°C.

Preparation Note

G418 powder is soluble in water at 50 mg/mL.
