Transformation (1) Got 3×100μL DH5α competent cells from the -70℃ refrigerator and divided them equally into six EP tubes, each for 50μL. (2) Wait for the solution to melt. (3) Add 10μL ligation system: 1-23L 7:1, 1-23L 3:1, 1-4H 7:1, 1-4H 3:1, 1-23L Control and 1-4H Control. (4) Keep in ice for 30min. (5) Heat shock in 42℃ for 90s. (6) Put the competent cells back into the ice box immediately for 2min. (7) Add 200μL antibiotic LB in a super clean bench and recover for 45min. (8) Centrifuge ,discard 100μL supernatant and smear the remaining 100μL onto the Amp+ plate. (9) Culture under 37℃.
