The bands extracted yesterday will be completed and digested using Taq ploymerase. We will use the the Taq polymerase mastermix.

The protocol will be:

25µL of Fermentas PCR mastermix (2x) 25µL DNA template

The PCR cycles will be:

80°C 1 min

80°C 30 sec
55°C 30 sec
72°C 30 sec

-> 10 cycles

72°C 5 min
4°C forever

The PCR product is treated with the PCR product purification kit. The tubes contains 20.1, 21, and 30 ng/µL resp.

Then the final product is ligated using T4 DNA ligate.

The mix contains:
- Linear DNA : 2µL   (40-50 ng final)
- 10 T4 DNA ligase buffer: 5µL
- 50% PEG 4000 solution: 5µL
- T4 DNA ligase: 1µL
- DNAse free water: 37 µL

Then it is incubated for 1h at 22°C.

10µL of the final product is then transformed by heat chock with 100µL of MH1 competent cells

Gel verification of Dave Lane plasmids

In a 1% agar gel, we have test our plasmids digested by XbaI and PstI enzyme. We've look if lines that we should see are the good one.
