Description

Streptomycin Sulfate (1:3) Salt) is a highly purified, water-soluble salt form of the classic aminoglycoside antibiotic streptomycin. This compound is critical for applications requiring a stable and potent antibacterial agent, particularly in research and diagnostic settings. It is primarily utilized by the pharmaceutical, biotechnology, and life science research industries for cell culture, microbiological studies, and as a selective agent in molecular biology.

Application

• Cell Culture & Microbiology: Used as an antibacterial agent in cell culture media to prevent bacterial contamination.
• Pharmaceutical Research: Serves as a reference standard and active pharmaceutical ingredient (API) in antibiotic research and development.
• Diagnostic Media: A key component in selective culture media for the isolation and identification of specific bacterial strains.
• Molecular Biology: Employed as a selective agent in genetic engineering and plasmid selection protocols.
• Veterinary Medicine: Used in the formulation of treatments for bacterial infections in animals.
• Agricultural Research: Applied in studies targeting plant bacterial diseases.
