G-418 disulfate

SKU: orb1227019

Description

An aminoglycoside antibiotic similar in structure to gentamicin B1; blocks polypeptide synthesis by inhibiting the elongation step in both prokaryotic and eukaryotic cells.(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.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. An aminoglycoside antibiotic, G418, has been shown to be an inhibitor of many pro- and eukaryotes at concentrations from 1-300 microgram/ml.
