Chapters
- 00:05Introduction
- 00:53Stress Treatment of E. coli Strains MG1655 and CFT073
- 02:12Collecting Bacterial Cell Samples
- 02:43Extracting the Insoluble Protein Aggregates
- 04:19Soluble Protein Sample Preparation
- 05:30Separation and Visualization of Extracted Protein Aggregates Using SDS-PAGE
- 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.
