LacZ (β-galactosidase) is used to monitor the transcription of genes in reporter strains carrying the lacZ gene under the control of a promotor of interest. This protocol for LacZ activity determinations in Vibrio cholerae following detergent lysis results in 2.5-fold increase of LacZ activities compared to lysis with chloroform.
