Kanamycin Sulfate is effective as a bacteriocidal agent by inhibiting ribosomal translocation and eliciting miscoding.  Resistance is conferred by the KanR-Tn5 gene product (aminoglycoside phosphotransferase), which modifies the antibiotic and prevents interaction with ribosomes. Liquid kanamycin (100X) contains 10 mg/ml kanamycin (base) utilizing kanamycin sulfate in 0.85% saline.
