- 06:49Results: Visualization of Protein Aggregates After Treatment of Escherichia coli with a Proteotoxic Stressor
- 07:32Conclusion
This protocol describes the extraction and visualization of aggregated and soluble proteins from Escherichia coli after treatment with a proteotoxic antimicrobial. Following this procedure allows a qualitative comparison of protein aggregate formation in vivo in different bacterial strains and/or between treatments.
