Description

G-418 disulfate (Geneticin sulfate), is an aminoglycoside antibiotic, inhibits protein synthesis in eukaryotes and prokaryotes. G-418 disulfate is commonly used as a selective agent for eukaryotic cells[1].

IC50 & Target

Aminoglycoside

 

In Vitro

G418 sulfate, an aminoglycoside neomycin analogue, interferes with protein synthesis and has been used extensively for selection of mammalian cell lines that possess neomycin resistance (NR). The neomycin resistance (neo) gene is frequently used in eukaryotic vectors as a dominant selectable gene. G418 can be covalently bound to asialoorosomucoid (AsOR) to form a conjugate for hepatocyte-specific targeting and toxicity[2].
The human GD3 synthase cDNA was transfected into MDA-MB231 cells, and G-418 bulk selection was used to select cells stably overexpressing the GD3 synthase[2]. An aminoglycoside antibiotic, G418, has been shown to be an inhibitor of many pro- and eukaryotes at concentrations from 1-300 microgram/ml[4].

Animal Administration
[3]

To characterize the sensitivity of the trypanosome populations to G418 in vivo, bloodstream forms of T. brucei brucei GUTat 3.1 and T. brucei brucei GUTat 3.1/BBR3 are expanded separately in sublethally irradiated mice. Prior to the first peak of parasitemia, trypanosomes are collected, and aliquots containing 106 trypanosomes are inoculated intraperitoneally into mice. Twenty-four hours following infection, the mice are divided into groups and treated with G418 at a dose of 10, 20, 30, 40, 50, or 80 mg/kg of body weight (bw) by inoculating intraperitoneally 0.2 mL of the drug in sterile water. At 24 and 48 h following the first treatment, G418 is administered to animals in each group at the same dose as before, resulting in three treatments per mouse. Repeated drug treatments are necessary to ensure complete elimination of nontransfected GUTat 3.1 parasites from the mice. Mice are then monitored daily, for 33 days, for the presence of parasites by microscopic examination of wet-blood films. Animals found to be parasitemic are recorded and then removed from the experiment.
