Cyrille

S24 + YFP-TetR:

  • Prepare the 9 miniprep
  • Replicate into glycerol
  • PCR colony was done

CP3008 PCRColony.jpg

YFP-TetR PstI-- 5re;oving the qdditionnal PstI site

  • 5 Miniprep prepared

Competent cell preparation of MH1


Axel

extraction of ComS from 5 different colonies

same protocol as those from the 17th of august:

We are going to extract the ComS gene from the PY79 strain. Oligo has been designed for this purpose.

  • Preparing the tube

Prepare 5 sterile tube with 20 µL of H2O for each colony Pick the colony using a pipetman woth a sterile tube. The pipetor is set at 3 µL for mixing

  • Dissolving the primers

Resuspend the primers adding 10µL of water by nmol of primer. Final concentration at 100 mM. Add 1µL in 2 ml of water to get the 50 µM

  • PCR mastermix 
60    µL HF phusion buffer
6      µL dNTPs
15    µL of colony mix
6      µL Primer fwd at (50µM)
6      µL Primer rev at (50µM)
157 µL of H2O

Aliquot 49 µL in 5 PCR tubes Add 1 µL of phusion in each tube.

  • PCR temperature 
1 - 98°C - 15 min
2 - 98°C - 30 sec
3 - 70°C - gradient +-10  - 1 min
4 - 55°C  - 1 min
5 - 72°C - 1 min
6 - Repeat 2-5 39 times
7 - 7°C forever

result of the gel: (biobricked ComS is about 160bp) ladder 100bp

ladder - col1 - col2 - col3 - col4 - col5 - control no colony


Camille

From the overnight culture I did minipreps, and obtained :

Strain [DNA] in ng/µL ratio
S38+pHyperspank 1 483.1 1.76
S38+pHyperspank 2 281.9 1.67

I sent them for sequencing.
