PRODUCT INFORMATION Kanamycin A Item No. 16140 CAS Registry No.: 59-01-8 Formal Name: O-3-amino-3-deoxy-α-D- OH OH glucopyranosyl-(1→6)-O- OH OH H O O [6-amino-6-deoxy-α-D- NH2 glucopyranosyl-(1→4)]-2-deoxy- O O D-streptamine OH H2N NH2 OH MF: C18H36N4O11 FW: 484.5 Purity: ≥95% H2N OH Supplied as: A crystalline solid Storage: -20°C Stability: As supplied, 2 years from the QC date provided on the Certificate of Analysis, when stored properly Laboratory Procedures Kanamycin A is supplied as a crystalline solid. Kanamycin A is sparingly soluble in organic solvents such as ethanol, DMSO, and dimethyl formamide. For biological experiments, we suggest that organic solvent-free aqueous solutions of kanamycin A be prepared by directly dissolving the crystalline solid in aqueous buffers. The solubility of kanamycin A in PBS, pH 7.2, is approximately 5 mg/ml. We do not recommend storing the aqueous solution for more than one day. Description Kanamycin A is a broad spectrum antibiotic isolated from a soil streptomyces (S. kanamyceticus). This aminoglycoside alters translation by prokaryotic ribosomes, resulting in bacterial cell death.1 In molecular biology, kanamycin A is used as a selective agent to isolate transformants that are expressing a kanamycin resistance gene, usually neomycin phosphotransferase (NptII/neo). This mode of selection is most commonly used in plant and mammalian biology. Reference 1. Misumi, M. and Tanaka, N.
