Using electroporation to transform Escherichia coli results in transformation efficiencies greater than can be obtained using the best chemical methods. It is easy to obtain transformation efficiencies 108 per milligram DNA and efficiencies of 1010 have been reported. This appendix describes a procedure for electroporation that can be used to transform many different types of bacteria.
