Antibiotic Selection in Bacterial Cloning: Use 50mg/mL Streptomycin Solution to select and maintain plasmids carrying streptomycin-resistance (aadA) in Escherichia coli.

Cell Culture Contamination Control: Use 50mg/mL Streptomycin Solution (often with penicillin) to reduce bacterial contamination in mammalian and insect cell cultures.

Plastid (Chloroplast) Transformation: Use 50mg/mL Streptomycin Solution for selection with aadA markers in plant and algal systems (e.g., Chlamydomonas reinhardtii).

Post-Transformation Plant Workflows: Use 50mg/mL Streptomycin Solution to eliminate residual Agrobacterium tumefaciens from plant tissues after transformation.

Microbial Media Supplementation: Use 50mg/mL Streptomycin Solution to suppress susceptible contaminants in LB, SOC, and other bacterial media.

Antimicrobial Susceptibility Testing: Use 50mg/mL Streptomycin Solution for MIC and disk diffusion assays against susceptible species such as Escherichia coli, Salmonella spp., and Mycobacterium spp.

Mutant Library Maintenance: Use 50mg/mL Streptomycin Solution to maintain streptomycin-resistant mutant collections in Escherichia coli and other bacteria.

Enrichment Cultures: Use 50mg/mL Streptomycin Solution to enrich for streptomycin-resistant strains from mixed microbial communities.
