Schematic map of the plasmid pMN86. The plasmid encodes origins of replication (Col E1, FI ori), a gene conferring resistance to the antibiotic ampicillin (amp), the thymidine kinase promoter (PTK) upstream of the Firefly luciferase gene (Fluc) and five copies of the Cd-responsive element (MRE). The MRE- PTK -Fluc cassette is flanked by two poly(A) signals to prevent transcriptional interference.
