Description

Kanamycin Sulfate is a water-soluble aminoglycoside antibiotic salt derived from *Streptomyces kanamyceticus*. It is valued for its broad-spectrum bactericidal activity, particularly against Gram-negative and some Gram-positive bacteria. This product is essential for research, pharmaceutical manufacturing, and in the production of cell culture media. Kanamycin Sulfate CAS NO 25389-94-0 is a critical reagent in molecular biology for selective pressure in bacterial cultures.

Application

• Pharmaceutical Active Ingredient: Used in the formulation of injectable antibiotic solutions and ophthalmic preparations.
• Microbiological Research: Serves as a selective agent in culture media for isolating and cultivating recombinant bacteria.
• Molecular Biology: A key component in genetic engineering for the selection of plasmids containing the kanamycin resistance gene.
• Cell Culture: Employed in mammalian cell culture to prevent bacterial contamination.
• Veterinary Medicine: Used in treatments for bacterial infections in livestock and companion animals.
• Agricultural Research: Applied in studies of plant bacterial diseases and the development of transgenic plants.
