Group: Flagella
Annealing of the two mutated strands of FlhDC
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
Primers used: None, as the two strands are supposed to anneal to each other
Results:
Gel extraction of flhD/C
Start date: 19/07 End date: 19/07
Methods: Gel extraction, nanodrop
Protocol:DE1.1
Experiment done by:Maria
Notes:
70uL of flhD/C PCR product from Amplification of flhD/C was loaded onto a 1.5 agarose gel and extracted according to protocol.
DNA was eluted in 20uL elution buffer.
Results:
Nanodrop:

Analysis:
Nanodrop measurements idicated a possible contamination. However the DNA was pooled and used for Digestion

Digestion of flhD/C and pSB1A2 with EcoRI SpeI
Start date: 19/07 End date: 19/07
Methods: Digestion, Gel electrophoresis
Protocol:RD1.1
Experiment done by:Maria
Notes:
purified pSB1C3 (tube 18 blue) and flhD/C from Gel extraction was digested with EcoRI and SpeI.

samples were loaded onto a 1.5 agarose gel. Gene ruler red were used as marker.
Results:
Gel electrophoresis:
Analysis:
In lane 2 containing pSB1C3 2 bands are detected indicating a succesful digestion of the plasmid (the band at 1000 bp corresponds to J04450). A succesful digestion of the flhD/C cannot be concluded from the gel. However both bands was excised and extracted from gel (Gel extraction)

Gel extraction of digested flhD/C and pSB1C3
Start date: 19/07 End date: 19/07
Methods: Gel extraction, nanodrop
Protocol:DE1.2
Experiment done by:Maria
Notes:
Digested flhD/C and pSB1C3 from Digestion were extracted from gel according to protocol.
DNA was eluted in 20uL H20.
