Kanamycin is used in molecular biology as a selective agent most commonly to isolate bacteria (e.g., E. coli) which have taken up genes (e.g., of plasmids) coupled to a gene coding for kanamycin resistance (primarily Neomycin phosphotransferase Streptomyces kanamyceticus ISP5500, S. fradiae ISP5063 and S. griseus ISP5236, which produce kanamycin, neomycin or streptomycin respectively, were highly resistant to the antibiotics they produced. You just need to titrate G418 concentrations which range anywhere . The bacterial neomycin-kanamycin phosphotransferase, type II enzyme is encoded by the neo gene and confers resistance to aminoglycoside drugs such as neomycin and kanamycin-bacterial selection and G418-eukaryotic cell selection. Genes conferring neomycin-resistance are commonly included in DNA plasmids used to establish stable mammalian cell lines expressing cloned proteins in culture. (Received . These antibiotics bind to ribosomal components and inhibit protein synthesis. The kanamycin resistance gene has natural origins and is found in Streptomyces kanamyceticus, a bacteria that is able to produce an enzyme that breaks down the kanamycin antibiotic before the antibiotic can destroy the bacteria.Any cell that can read this gene and transcribe the resultant enzyme will have a resistance to kanamycin. Of the two antibiotic resistance genes found by FDA, one confers Neomycin/Kanamycin resistance and the other Ampicillin resistance. … Neomycin phosphotransferase II confers resistance to kanamycin and neomycin in bacteria and G418 (Geneticin®, G418 Sulfate) in mammalian cells. molecular biology - Neomycin resistance gene in E. coli ...

The nptII gene confers transgenic plants resistance to the antibiotic, kanamycin, kan, and the hptII gene provides transgenic plants resistance to the antibiotic, hygromycin, hyg [3,5]. Abstract. Like pCIneo vector, for example, with neo gene for mammalian cells selection using G418, and bla gene for Amp selection of bacteria, then the neo gene in this case won't help bacteria . Kanamycin resistance gene (kmr) from the overproducing mutant strain of Streptomyces kanamyceticus ISP1375 (strain 1) and from its gentamicin-resistant mutant were cloned into the high copy number vector pIJ702 and transformed into S. lividans 66. It would if the neo gene is under bacterial promoter, but not if it is for mammalian selection. Polyphenylalanine synthesis in cell free systems was also resistant to the action of the antibiotics. The gene is widely used as a selectable marker in the transformation of organisms as diverse as bacteria, yeast, plants, and animals. The neo (neomycin-resistance) gene of transposon Tn5 encodes the enzyme neomycin phosphotransferase II (EC 2.7.1.95), which confers resistance to various aminoglycoside antibiotics, including kanamycin and G418.
