Place electroporation tanks in ice for 10min
Take samples of plasmids (25ng-50ng/µL) /!\ Keep them in ice /!\
Take sample of competent cells /!\ Keep them in ice /!\
Place 1µL of plasmid in the sample of competent cells
Transfer the full volume obtained in the electroporation tank
Place in the electroporator and pulse at 2000V
NB: The optimal pulse length is between 5 and 6ms.
