Annealing of the two mutated strands of FlhDC (FlhDCmut)
Experiment done by: Sheila
Date: July 19th
Protocol: CP1.1
Method: PCR of the two mutated strands of the FlhDC operon
Notes: To samples were run at two different temperatures: 56,1˚C and 64,5˚C respectively.
Polymerase used: Pfu

Transformation of cells with gene in plasmid
Date: 21/7
Methods: Transformation
Protocols: TR1.1 and paperblotter protocol from plasmid cDNA package.
Notes: Filterpaper was washed with 50ul TE buffer for 2 seconds. Paper punch was then transfered to a sterile eppendorff tube, and transformation protocol TR1.1 was followed from here. The usual positive control was used.
Plates were dried for ca. 12 minutes, showed no sign of cracking.
The gene is inserted into a pOT2 plasmid. A plasmid map can be found [http://www.fruitfly.org/about/methods/pOT2vector.html here]:
Two of the chlor plates were damaged (one very slightly) and one ampicilin plate was torn up, again. (good thing two were dried). Plates were incubated ON at 37°.
