Fig. 3From: Heterogeneous oxygen availability affects the titer and topology but not the fidelity of plasmid DNA produced by Escherichia coli pDNA topological analyses. a Agarose gel electrophoresis images of pDNA samples through the cultivation time; b Chip electrophoresis electropherograms; c virtual gel agarose electrophoresis images of pDNA samples from the end of the cultures. SC indicates the pDNA supercoiled fraction; M denotes DNA markers; 1 and 2 indicate the two major pDNA populations foundBack to article page
