Week 3


From Monday the 27th of June to Friday the 1st of July 2011







Monday


Another PCR is launched to collect more DNA from MC4100 (Failure).
Culture of the wrong strains for the transformation...(Failure : the strain already had a plasmid)
Alcoholic precipitation of PCR product from the previous week.



Tuesday


Culture of NM522 cells for later transformations and Curli for extraction.

Ligation of PCR products in pGem-T easy vector to make them standard parts. Transformation in NM522 strain of the ligation product. Selection on ampicilline, X-Gal, IPTG plate. Only CsgAB was not transformed this day.





Wednesday


CaCl2 chemical transformation ( V=10mL, 2µL DNA ) of some iGEM kit distribution DNA :

Plate 1 :
18A (constitutive promoter, Amp )
2M ( strong RBS, Amp )
5L ( weak RBS, Amp )
22M ( RBS+YFP, Amp)

Plate 2 :
24E (YFP, Amp + Kan )
2L (GFP, Amp )

Selection of white colonies on the plate for part RcnR and CsgEFG. Liquid culture for miniprep.

Transformation in NM522 of part CsgAB.





Thursday


Miniprep using the QuickPure kit, digestion and electrophoresis of the Curli plasmid.

Start of liquid cultures of two individual clones for each of the 6 iGEM plasmids
Miniprep using the QuickPure kit of the 18A, 2M, 22M, 24E and 2L plasmids.

Miniprep of clones with CsgEFG and RcnR. Digestion of plasmid with EcoRI to check part insertions.


The local newspaper "VIVA" interviewed us. They asked about our project, our team and about iGEM's organization.





Friday


Miniprep using the QuickPure kit of 5L plasmid.

Ozyme digestion with :
S + P : 18A, 2M, 5L
X + P : 22M, 2L, 24E

Electrophoresis of the digested plasmids versus the non digested.
-> All the strains had the correct plasmid : they were plated on LB + amp medium.

Miniprep of clones with Csg AB. Digestion of plasmid with EcoRI. Send to GATC for sequencing.
