Plasmid DNA from Escherichia coli for antibiotic-free genome integration.
The plasmid DNA was purified from Escherichia coli NEB5α and consists of 8280 bp (MW ~ 5.1 x106 Da). The pAIO plasmid is equipped with all elements for “All-In-One” genome integration. The λ-red enzymes Exo, Gam and Bet under control of a heat inducible promotor were selected to ensure the integration of a linear target gene cassette into the E. coli genome. The gene encoding the homing endonuclease I-SceI was inserted into the vector under control of the araB promoter for selection purpose and plasmid curing. To provide accelerated plasmid curing, we engineered an additional I-SceI site into the plasmid backbone, with the idea that the plasmid also gets cleaved upon the expression of I-SceI.
