ABSTRACT:
Gene products of plasmid DNA, such as proteins, are prepared in high yields by cultivating bacteria carrying a plasmid which shows a controlled constant plasmid copy number at one temperature and a much higher or totally uncontrolled copy number at a different temperature. The plasmid may be prepared by recombinant DNA technique using a cloning vector showing the temperature dependent plasmid copy number pattern.
