Kanamycin Sulfate 50mg/ml Solution (Streptomyces kanamyceticus, Kanamycin A, Kanamycin monosulfate )

Kanamycin sulfate is an antibiotic that belongs to the group of drugs called aminoglycosides. It binds to ribosomal components and inhibits protein synthesis. Kanamycin sulfate appears to prevent bacteria from making their cell walls, thus the cells die. It is used to treat many sensitive gram-negative, some gram-positive bacteria and and mycoplasmas in cell culture. Kanamycin is inactivated by an aminoglycoside phospho transferase (MW 25,000) in the periplasmic space.
