Kanamycin is an aminoglycoside antibiotic isolated from Streptomyces kanamyceticus.It is effective against gram-positive and gram-negative bacteria as well as Mycoplasma species.Kanamycin is commonly used to select for bacteria that have been transformed with a kanamycin-resistant gene and plant tissues that have the NPT II (APH3) gene incorporated in them.Kanamycin is very soluble in aqueous solution and is typically used in concentrations of 50-100 µg/ml.

Aminoglycoside antibiotics are composed of amino groups attached to glycosides. They bind the 30s ribosomal subunit, causing misreading of the mRNA sequence and inhibition of translocation. Consequently, protein synthesis is inhibited.

Antibiotics are often used in clinical in vitro tests known as antimicrobial susceptibility tests or ASTs to determine their efficacy against certain bacterial species. They are tested against gram-negative and gram-positive bacteria using panels, discs, and MIC strips by medical microbiologists. ASTs decrease the risk of using an antibiotic against bacteria exhibiting resistance to it, and the results are used in clinical settings to determine which antibiotic(s) to prescribe for various infections.
