Used as a selective agent in cell culture and microbiology to isolate genetically modified organisms, particularly in bacterial transformation experiments where resistance genes are introduced. Commonly applied in molecular biology for maintaining plasmid constructs in E. coli and other host cells. Also utilized in veterinary medicine to treat bacterial infections, especially those caused by Gram-negative pathogens. In research, it serves as a tool for studying protein synthesis inhibition since it targets the 30S ribosomal subunit.
