Transforming Electrocompetent E. coli Cells. On ice, add 1-2ul of ligation reaction to 40ul of electrocompetent cells, mix gently and incubate for 1 min. Transfer cells/DNA to iced 0.2cm electroporation cuvette, tap cells to the base of the cuvette. Set Micropulser to E2 (setting for 0.2cm cuvettes), slide cuvette in to chamber and pulse once.

This protocol differs from other procedures in that the bacterial culture is grown at 18ºC rather than the conventional 37ºC. Otherwise, the protocol is unremarkable and follows a fairly standard course. Why growing the cells at low temperature should affect the efficiency of transformation is anybody's guess.
