Description

Kanamycin Sulfate is a broad-spectrum aminoglycoside antibiotic derived from *Streptomyces kanamyceticus*. It is essential for inhibiting the growth of a wide range of Gram-negative and some Gram-positive bacteria. This product is critical for research and development, pharmaceutical manufacturing, and microbiological applications. Kanamycin Sulfate CAS NO 70560-51-9 is a fundamental tool in molecular biology, cell culture, and the production of therapeutic agents.

Application

• Molecular Biology & Genetic Research: Widely used as a selective agent in bacterial cell culture and for the selection of genetically modified cells containing kanamycin resistance genes.
• Pharmaceutical Manufacturing: Serves as an active pharmaceutical ingredient (API) in the formulation of injectable antibiotics for treating serious bacterial infections.
• Microbiological Media: Incorporated into agar plates and liquid culture media to prevent bacterial contamination in sterile cell culture work.
• Veterinary Medicine: Used in the treatment of bacterial infections in livestock and companion animals.
• Biotechnology & Fermentation: Employed to maintain plasmid stability in large-scale microbial fermentation processes for protein or metabolite production.
• Agricultural Research: Applied in plant tissue culture to select for transgenic plant cells and prevent microbial overgrowth.
