This protocol differs from other transformation procedures in that the bacterial culture is grown at 18°C rather than the conventional 37°C. Otherwise, the protocol is unremarkable and follows a fairly standard course. Under standard laboratory conditions, efficiencies of 1 × 108 to 3 × 108 transformed colonies/µg of plasmid DNA are typical.
