The determination of the number of plasmid copies in each cell of Lactococcus lactis is critical for the control and regulation of the production of recombinant proteins and plasmids. This protocol describes a method for the determination of the plasmid copy number per genome of L. lactis, which is based on the detection by real-time quantitative PCR of the number of plasmid molecules and the number of chromosomes and subsequently their ratio after calculating the amplification efficiency.
