Cloning cartridges comprising a positive regulatory gene nahR from plasmid NAH7, a promoter Pg that is regulated by nahR, a multiple cloning site, a transcription terminator, and a gene conferring tetracycline resistance. Such cartridges can be inserted into plasmids of choice to form novel expression vectors in which high level gene expression is inducible with an inexpensive non-toxic inducer at low concentrations. |
