Description générale

Chemical structure: aminoglycoside
G-418 is an aminoglycoside antibiotic, which is produced by Micromonospora rhodorangea NRRL 5326 strain. It has a broad range of antibacterial activity both in vivo and in vitro. It also shows activity against protozoa, cecal amoebiasis, and helminthes.[1] It is commonly known as geneticin selective antibiotic.

Application

G418 disulfate salt is an aminoglycoside antibiotic similar in structure to gentamicin used for selection and maintenance of prokaryotic and eukaryotic cells[2][3][4] 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.

Conditionnement

1, 5, 25 g in glass bottle

Actions biochimiques/physiologiques

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.[5]

Attention

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

Notes préparatoires

G418 powder is soluble in water at 100 mg/mL.

Autres remarques

Keep container tightly closed in a dry and well-ventilated place. Keep in a dry place.
