Co-transformation Transform two plasmids (A+, C+) to MG3.① Plac-CheZ-His-TT C+② Lac Iq A+
14:10 Subculture to warm room (37℃), shaking for 1.5h.
15:40 take the subculture bacteria out from the warm room.Freeze the bacteria in 0℃ ice water for
15min.Centrifuge in 4000rmp at 0℃ for 2min.Decent supernatant
Add iced DI water, re-suspend Centrifuge in 8000rmp for 2min. Pipette away supernatant. (Above three steps should be repeated for 3 times.) Remove most supernatant, leaving behind~50μL. Electro-transformation
15:40 Recover in warm room (37℃) for 1h.
18:40 take the bacteria out from warm room
Transfer to agar plates with A+ & C+.
