G-418 sulfate, also known as geneticin, is an aminoglycoside antibiotic similar in structure to gentamicin B1.It is commonly used in plant and mammalian cell culture as a selectable marker.It can be used to select for cells transformed with an iNOS promoter construct or neomycin resistance gene.
G-418 functions by causing a chain of nonsense mutations during translation, ultimately resulting in inhibition of polypeptide synthesis and protein elongation. Resistance to G-418 is conferred through the nptll gene in plant cells and the neo gene in mammalian cells, which encode aminoglycoside 3"-phosphotransferase.For gene selection applications, a kill curve can be made to determine the minimum effective G418 concentration to kill non-resistant cells.G418 disulfate is freely soluble in water.
This product has been tested against both sensitive and resistant cells at Gold Biotechnology Labs.
