Module I, group 2(b)
Ligate PEMK with C. Using the PEMK①.
Double digestion system:
chlr:
H2O 5μl buffer Tango 2μl chlr 10μl KpnI 3μl Total 20μl 37℃ 1h, then + buffer Tango 2.5μl + EcoRI 1μl Total 23.5μl
PEMK:
H2O 3μl buffer Tango 2μl PEMK 12μl KpnI 3μl Total 20μl 37℃ 1h, then + buffer Tango 2.5μl + EcoRI 1μl Total 23.5μl
Run a gel and cut to purify the digestion products. Measure the concentration. Ligate the PEM and PC with K.
Ligation system:
PEMK+C:
H2O 14.4μl 10×buffer 2μl C 1μl PEMK 1.6μl T4 ligase 1μl Total 20μl
Transform the ligation product into bacterial cells immediately. Spread about 100μl of the resulting solutions on LB plates (with 0.1% ampicillin).
Module I, Group 2c
Ligation product is transformed in to DH5aα 24h after ligation.
