Week 4


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







Monday


Another PCR is launched to collect more DNA (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


Miniprep, digestion and electrophoresis of the Curli plasmid.

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

Transformation in NM522 of part CsgAB.





Thursday


CaCl2 chemical transformation 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 )

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


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





Friday


Miniprep using the QuickPure kit of the previous 6 iGEM parts.

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.
