Construction and Use of Flow Cytometry Optimized Plasmid-Sensor Strains: Genomes in Flux

Determining the stability of plasmids in bacterial populations is traditionally performed by isolating a large number of clones followed by screening for the presence of plasmids by replica transfer to plasmid-selective agar plates. This is often a laborious task, especially when the intrinsic stability of the plasmid is high. The method presented here relies on a phenotypic (green fluorescence protein) marker, which is switched on if the host bacteria loses the residing plasmid. The incorporation of flow cytometry for single-cell detection and discrimination between plasmid-free and plasmid-harboring cells in a bacterial population facilitates a very high throughput of cells and thus provides excellent sensitivity and statistics toward detecting even very low levels of plasmid instability.
