Kanamycin A Sulfate, EvoPure® is the highly purified sulfate salt form of Kanamycin A.  Kanamycin A is the major component of the Kanamycin complex (minor components include Kanamycin B and C).  The product is ≥99.0% pure by HPLC.

Kanamycin is a semi-synthetic, broad-spectrum aminoglycoside antibiotic.  Kanamycin was isolated from the soil bacterium Streptomyces kanamyceticus in 1957 by Hamao Umezawa at the institute of Microbial Chemistry (Tokyo).  Kanamycin inhibits protein synthesis in bacteria and Mycoplasma.  It is used to select for transformants (bacteria, fungi, plant, mammalian) which have been successfully transformed with a plasmid containing a kanamycin resistance gene. 

Kanamycin A Sulfate, EvoPure® is soluble in water. It is practically insoluble in ethanol, DMSO, acetone, chloroform, ether and ethyl acetate.

We also offer:

  • Kanamycin Sulfate (K008)
  • Kanamycin Acid Sulfate, BP (K004)
  • Kanamycin Acid Sulfate, EP (K029)
  • Kanamycin B Sulfate, EvoPure® (K014)

Kanamycin EvoPure® products are available as highly purified fractions (see Technical Data).  Each compound is fully characterized by spectral analysis and a comprehensive C of A is provided which includes HPLC, MS, HNMR and FTIR data.

    CAS Number


    Molecular Formula

    C18H36N4O11· xH2SO4 (lot specific)

    Molecular Weight

    484.50 g/mol (Free base)

    Mechanism of Action

    Aminoglycosides target the 30S ribosomal subunit, lodging between the 16S rRNA and S12 protein. This interferes with the translational initiation complex causing misreading of the mRNA, and production of a faulty or nonexistent protein.

    Storage Conditions

    -20 °C

    Tariff Code



    Kanamycin is a broad-spectrum antibiotic with bactericidal activity, used mostly against Gram-negative bacteria.



    The product can be used as a reference standard, in impurity profiling, and to analyze the individual effects of the Kanamycin A fraction .

    Cancer Applications

    Kanamycin was used in an experimental mouse model of colorectal cancer. Following short-term induction of colitis by an irritant (dextran sulfate sodium), colon cancer cells (colon 26) were instilled intrarectally. The result was that tumors formed at the luminal mucosal surface. This model is useful to examine chemotherapeutic agents that may suppress the growth of colorectal cancer (Takahashi et al, 2004).

    Eukaryotic Cell Culture Applications

    Kanamycin Sulfate was used in an in vitro model system of Henle intestinal epithelial cell infection (Henle 407 cell line) by Shigella flexneri. Bactericidal levels of Kanamycin ablated infectivity of Shigella (Hale and Bonventre, 1979).

    Microbiology Applications

    Kanamycin is commonly used in clinical in vitromicrobiological 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.  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
    Perfringens Agar - SFP and TSC selective supplements for the isolation of Clostridium perfringens

    Plant Biology Applications

    Kanamycin is often used in the Agrobacterium-mediated transformation using the neomycin phosphotransferase gene (npt II gene) as a selection marker which confers resistance to kanamycin (and G418).

    Gene transfer to cereal cells (Triticum monococcum)  mediated by protoplast transformation with naked DNA. Plasmid contained a gene of interest along with the NTP II gene and after insertion, and transformed cells were selected on medium containing Kanamycin (Lorz et al 1985).

    In a study of drought and salt tolerance, soybeans (DT84 cultivar) were genetically modified using Agrobacterium-mediated transformation to insert the GmDREB6 gene along with the nptII gene to select for plants resistant to kanamycin.  GmDREB6 is a dehydration-responsive element binding proteins (DREBs), a plant transcription factor that binds to specific region of promoter to activate expression of mechanisms to cope with cellular dehydration. Overexpression of GmDREB6 increased transcription levels of GmP5CS gene, which caused a higher intracellular proline content in plants growing under salt stress (Nguyen et al, 2019).
