At the same time, intact shuttle-plasmid pZ189 was also introduced into the host cell which was used for detection of nontargeted mutation frequency. After replicating in cells, progeny plasmid DNA was isolated and transformed into E coli. MBM7070.In the presence of ampicillin, X-gal and IPTG, pZ189-transformed E. Coli MBM7070 forms blue colony if the plasmid contains an active SupF suppresser tRNA gene, and white or light blue colony if the SupF tRNA gene is inactive.
