  • Description

    Kanamycin is an aminoglycoside antibiotic often used to select for plants (Agrobacterium mediated transformation) and bacteria which have been successfully transformed with a plasmid conferring kanamycin resistance.  Kanamycin is very soluble in aqueous solution at 92.3 mg/mL.

    Standard grade kanamycin is composed of a mixture of three different fractions: kanamycin A, B, and C. TOKU-E offers five forms of kanamycin:

    EvoPure® products are purified single antibiotic fractions, most >99% pure. High purity EvoPure® kanamycin products can be used to analyze the specific effects of individual kanamycin fractions.

    Mechanism of Action

    Aminoglycosides target the 30S ribosomal subunit resulting in an inability to read mRNA ultimately producing a faulty or nonexistent protein.


    Kanamycin is a broad spectrum antibiotic, however, it is mostly used against aerobic Gram-negative bacteria.

    • Microbiology Applications

      Kanamycin is commonly used in clinical in vitro microbiological antimicrobial susceptibility tests (panels, discs, and MIC strips) against gram positive and gram negative microbial isolates. Medical microbiologists use AST results to recommend antibiotic treatment options for infected patients. Representative MIC values include:

      • Salmonella enteritidis 62.5 µg/mL
      • Escherichia coli 31.2 µg/mL

      Media Supplements

      Kanamycin can be used as a selective agent in several types of isolation media:

      Kanamycin Aesculin Azide AgarEnterococci isolation in food

    • Plant Biology Applications

      Kanamycin is often used in Agrobacterium mediated transformation using the npt II gene as selection marker. Kaur and Bansal (2010) used kanamycin in combination with cefotaxime to control bacterial growth while transforming tomato.
