Kanamycin: A Broad Spectrum Aminoglycoside Antibiotic and a Selective Reagent Genetically Engineered Cells

Kanamycin, an aminoglycoside antibiotic, was first isolated in 1957 from the bacterium Streptomyces kanamyceticus by Umezawa. Kanamycin has broad activity against Gram-negative bacteria and Gram-positive bacteria, including Mycobacterium tuberculosis. Kanamycin interacts with the 30S subunit of prokaryotic ribosomes, and then it inhibits bacterial growth by inhibiting protein synthesis. Kanamycin is used in molecular biology as a selective reagent most commonly to isolate bacteria (e.g., Escherichia coli.) coupled to a gene coding for kanamycin resistance, which is one of the most frequently used selection markers for obtaining transgenic cells.
