DNA transfection of Escherichia coli by electroporation.


Electroporation was applied to transfection and transformation of Escherichia coli. Efficient transfer of DNA was achieved by a single voltage pulse at 2.5 kV (initial electric field strength = 6.25 kV/cm), with a 25 microF capacitor. As the recipient for transfecting DNA in the electroporation, spheroplasts, EDTA-treated cells and osmotically shocked… (More)
