A fluorogenic substrate and trapping reagent have been used to detect β-galactosidase activity expressed in S. cerevisiae from an Escherichia coli lacZ gene segment encoded on a recombinant plasmid. The measurement may be made in less than 1 msec using a flow cytometer, facilitating rapid experimental characterization of plasmid instability.
