Lab work

D - Lemon Scent

pPSI digestion

components volumes
pPSI 40μl
FastDigest green buffer 10X 5μl
PacI 2µl
H2O 2µl

pPSI dephosphorylation

After 2 hours, add 1.5µL of Alkaline Phosphatase (AP) and let it 1 hour.

Then, inactivation of AP at 65°C during 15 minutes.

We've made a electrophoresis to check the digestion.

And let it in the freezer for 3 hours.

Transformation in competent E.coli DH5α

After 3 hours, take out the ligation tubes and add 100 µl of competent DH5α in each tube.

Then proceed to the transformation protocol.

- 20 minutes at 4°C

- 2 minutes 30 seconds at 42°C

- 2 minutes at 4 °C

- Add 0.9 ml of LB into the tubes

Finally put it in a incubator at 37°C for 30 minutes
