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
Primers used: None, as the two strands are supposed to anneal to each other

Pfu buffer	5,0uL
dNTP	1,5uL
FlhDC mutated long strand	1,5uL
FlhDC mutated short strand	1,5uL
H2O	41,0uL
Pfu	1,0uL

The samples were run in the following PCR program:

Program	1st sample	2nd sample	Time
1: Start	94˚C	94˚C	3min
2: Denaturing	94˚C	94˚C	2min
3: Annealing	56,1˚C	64,5˚C	30sec
4: Elongation	72˚C	72˚C	2min
5:	GOTO	Repeat	X29
6: End	72˚C	72˚C	2min
7: Hold	4˚C	4˚C

Results: A gel, containing the PCR product was run, using [http://www.fermentas.de/product_info.php?info=p1110 GeneRuler(TM) DNA Ladder Mix, ready-to-use (#SM0333)] loaded in lane one (from the left:


We can se very faint bands in lane 2 and 3, at around 1000bp. The band in lane 3 is a little more visible than lane 2. Because we haven't used primers ind this PCR, it is possible that the two mutated strands has a lower possibility of annealing to each other. It s however possible to amplify the few complete FlhDCmut strands in a new PCR, which is what we will do next.

Amplification of FlhDCmut

Experiment done by: Sheila

Date: July 19th

Protocol: CP1.1

Method: The experiment was done in two rounds. First, the annealing product, made by Pernille on july 19th was amplified. Then we amplified Pernilles amplification simultaneously as we amplified Sheilas previous annealing.
Primers used: FlhDC fw and FlhDC rev
Polymerase used: Pfu

Restriction digest of FlhDCmut and pSB1C3 X2

Experiment done by: Sheila

Date: July 20th

Protocol: RD1.1

Method: 'Premixes:'

FlhDCmut	X1	X3
H2O	12µL	36µL
FD Green Buffer	2µL	6µL
Enzyme A: EcoRI	1µL	3µL
Enzyme B: S	1µL	3µL

pSB1C3	X1	X3
H2O	12µL	36µL
FD Green Buffer	2µL	6µL
Enzyme A: EcoRI	1µL	3µL
Enzyme B: X	1µL	3µL

The digested samples were then run on a 1,5% agarose gel for approximately 20 minutes

Results: Because it failed the first time, this experiment was repeated, with the same results (see notes section)

The first gel

The second gel

The gels do not show any sign of a successful digest. Because the restiction enzymes only cut in the prefix and suffix of the FlhDCmut operon, it is not surprising that we do not see any bands of approximately 10bp length. However, the digestion should be very clearly visible in the plasmid backbone, as we should be cutting out RFP, which is approximately 1000bp long. The plasmid do not appear to have been digested by the restriction enzymes. 2 bands are visible, but they are both much longer than expected, in fact they appear around the length of the complete plasmid. So this experiment appears to have been unsuccessful.

Notes: First troubleshooting session led to a repeat of the experiment, as we found that human error must have been the reason for the failed results, because it was the first time i performed the experiment. However, when the repeat of the restriction digest yielded the same results, we took a closer look and found that the combination of restriction enzymes was wrong. They were the combination we will use when we begin the assembly... In this case we want to insert the biobrick (FlhDCmut) into the plasmid backbone (pSB1C3, in which case we need to use the same restriction enzymes on both the plasmid and the biobrick.

Gel extraction of FlhDCmut and pSB1C3 X2

Experiment done by: Sheila

Date: July 20th and July 21st

Protocol: DE1.3

Method: The samples were run on a 1,5% agarose gel.

Notes: No restriction were seen in the pSB1C3 lane, which lead to the conclusion that the restriction digest failed (see above. The FlhDC was extracted from the gel in order to amplify it with PCR

Results:

2: Denaturing	94C	1 min
3: Annealing	55C	1 min
4: Elongation	72C	1 min 30 s
5:	GO TO	rep. 29x
6: End	72C	3 min
7: Hold	4C

PCR product was loaded onto a 2% agarose gel. Gene ruler DNA ladder mix (red) was used as marker.

VF2 - coding sequence (in pSB1C3) : 140bp
Coding sequence - VR (in pSB1C3)  : 176bp
flhD/C  : 932bp
VF2 - VR for pSB1C3 w. flhD/C  :1248bp

VF2 - VR for pSB1C3 without insertion : 316bp

Results:
Gel electrophoresis:

Analysis:
All lanes except 4, 9 and 10 showed a band at app. 1200bp. which might indicate plasmids where flhD/C has been inserted. Lane 4 and 9 has a band at app. 1500bp which could indicate undigested pSB1C3 (VF2 - VR for pSB1C3 w. J04450 is 1385bp).
Streak plates of coloni 1, 2, 3, 5, 6, 7, 8 and 10 showed red colonies, indicating that these contained undigested pSB1C3.
Streak plates of coloni 4 and 9 had only white colonies, suggesting an insertion has occured.
To verify if flhD/C has been inserted coloni PCR using VF2 and flhD/C rev. as primers was carried out for colonies from streak plates of coloni 4 and 9 and of all white colonies from the transformation plates. (see coloni PCR)

6: End	72C	3 min
7: Hold	4C

PCR product was loaded onto a 2% agarose gel. Gene ruler DNA ladder mix (red) was used as marker.

Results:
Gel electrophoresis:

Analysis:
None of the samples contained amplified DNA.
This indicates either that the flhD/C gene has not been inserted to the pSB1C3 backbone or an insertion has been made but the flhD/C primer has not been able to anneal to the template.
To verify that a ligation has occurred, PCR product 4 and 9 from Coloni PCR was digested with EcoRI and SpeI.

Digestion of flhD/C PCR product with EcoRI and SpeI

Start date: 24/07 End date: 24/07
Methods: Restriction digest and gel electrophoresis

Protocol:RD1.1

Experiment done by: Maria

Notes:
To verify if a ligation has occurred Taq PCR product of coloni 4 and 9 (see Coloni PCR) was digested with the same restiction enzymes used for the digestion of flhD/C DNA and pSB1C3 prior to ligation.
If an ligation has occurred, then the restriction sites of EcoRI and SpeI should be intact, and two fragments of 122bp and 170bp should be observed on the gel, indicating VF2-E site and S site-VR respectively.
RFP (PCR poduct of coloni no.8) was used as controle.
2.5uL of undigested PCR product of coloni 4, 8 and 9 were loaded onto the gel as well.
Samples were loaded onto a 2% agarose gel. Hyper Ladder II was used as marker.
Loading scheme:

Lane	1	2	3	4	5	6
	digested no. 4	undigested no. 4	digested no. 9	undigested no. 9	digested no. 8	undigested no. 8

Results:
Gel electrophoresis:


Analysis:
The 2 bands at app. 100bp and 200bp respectively indicates that the E and S restiction sites have been preserved, suggesting that a ligation has occured.
An ON culture of coloni 4 and 9 is made to use for mini-prep.

Notes:
To verify if the silent mutation has been made PCR product of flhD/C mut (see [flhD/C mut PCR] was digested with restiction enzyme PstI.
If the mutation has been made the flhD/C fragment should not be digested with PstI.
PCR product of flhD/C (native coding sequence) was used as controle.
Undigested PCR product of flhD/C (native coding sequence) was loaded onto the gel as well.
Samples were loaded onto a 2% agarose gel. Hyper Ladder II was used as marker.

Purification of pSB1A2 containing J13002

Experiment done by: Pernille

Date: the 19 of July

Protocol: MP1.1 and CP1.1

Method: Miniprep, Nano drop, gel electrophoresis and PCR

Notes: The pSB1A2 plasmid are a high-copy-plasmid and therefore 5mL ON culture are used for purification of the plasmid. for the PCR the following PRC program are used: 1: 94°C 3min 2: 94°C 2min 3: 55°C 30 sec 4: 72°C 1min 5: x 29 rep. 6: 72°C 5min 7: hold 4°C

Results:After the purification the concentration of nucleic acid concentration was measured on the Nano Drop. There was made four purification tubes. Only tube 1 and 3 was used for further experiments because the other contained a very low concentration of nucleic acid. The concentration in tube 1 and 3 was 25,72ng/uL and 25,76ng/uL. The purified DNA was loaded in a 1,5% agarose gel together with a 10.000bp long ladder (red).

PCR was run on the DNA using the VR and VF2 primers wich ensures the only the brick part are amplificated. The pfu polymerase was used but unfortunately i did not get any results since i did not add any MgSO4 to the premix.

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°.

Results: Colonies showed on all plates.

Transformations have been succesfull. If our gene is in there will be tested next week.
