I use an electroporation method almost exactly the same as this and it
works reliably.  However, I cannot get electroporation efficiencies
greater than around 15-20% of the total surviving cells.

Does anyone have any comments, suggestions or alternative methods (e.g.
lipofection) to improve this efficiency?

Thanks in advance,

Alan.
