=== Checking if Pst1 site in FlhDC mut is not pressent vol.2 ===
 +
''Done by:'' Sheila & Louise <br>
 +
''Date:'' August 2nd <br>
 +
''Protocol:'' [https://2010.igem.org/Team:SDU-Denmark/protocols#RD1.1 RD1.1] <br>
 +
''Notes:'' Freeze tube 9 containing DNA purification from MG1655 cells was used as native FlhDC. Freeze tube 48 containing FlhDC mut purification. These two samples was amplified according to [https://2010.igem.org/Team:SDU-Denmark/protocols#CP1.1 CP1.1] and run with an annealing temperature of 63 celcius and 2 minutes elongation. <br>
 +
The PCR samples were loaded on a1.5% gel with two ladders (100-1000 and 100-10000) FlhDC native was loaded in the first 5 lanes and FlhDC mut in the next 5 lanes. <br>
 +
The gel is expected to show two bands for the native FlhDC gene, one arround 900bp and one arround 100bp, while the FlhDC mut is expected to show only one band, between 900bp and 1000bp. <br>
 +
''Results:'' The gel is pour, shows smear and bands at 200 bp. <br>
 +

 +
<br>
 +
We suspect that the primers are to blame for this result. It is possible that when the primer-stock used was made, old primers was used instead of the new longer ones. If this is the case then the annealing temperature of 63 celcius (ajusted to the new primers) is way higher than that of the old ones (45 celcius) which would make it impossible for primers to anneal. <br>
 +
So we made new primer-stock, and removed the old stock and primers. <br>

''Notes:'' The previous experiment was redone with the new primers. <br> Five samples of native FlhDC (FT 9) and 3 samples of FlhDC mut (FT 48) was loaded on a 1.5% gel with two ladders (100-1000 and 100-10000). <br>
 +
''Results:'' The gel still shows smear and bands at 200bp. <br> We have no explanation this time, and have desided to shelve this experiment a while. <br>

In the picture U = Uncut, P = Pst1 and S = Spe1. The Native FlhDC has an internal Pst1 site, while this site has been altered in the FlhDCmut gene. As expected all the cut samples show two bands, while the uncut samples only show one band. The picture shows a difference between the cut band and the greatest cut band in the native FlhDC, the cut band is slightly leighter than the uncut (ca. 100bp). The FlhDCmut samples show no specefic difference between the uncut band and the greatest cut band. <br>
 +
This indicates that a grater part of the native FlhDC is cut of than is cut of the FlhDCmut. <br>

=== Colony PCR of FlhDCmut and DT (B0015) ===

''Done by:'' Maria, Pernille & Louise <br>
 +
''Date:'' August 4th <br>
 +
''Protocol:'' [https://2010.igem.org/Team:SDU-Denmark/protocols#CP1.3 CP1.3] <br>
 +
''Notes:'' The FlhDC mut gene was previously incearted into two different plasmids (pSB3k3 and pSB1c3) and the DT was incearted into pSB3c5. These were grown and 8 colonies from different plates were picked<br><br>
 +
FlhDCmut in pSB3k3, PCR-tube 1a-h <br>
 +
- 1a, -b, -c were picked from plate L1.1b (30.07.10) <br>
 +
- 1d, -e, -f were picked from plate L2.1a (30.07.10) <br>
 +
- 1g, -h were picked from plate L3.2a (30.07.10) <br><br>
 +
FlhDCmut in pSB1c3, PCR-tube 2a-h <br>
 +
- 2a, -b were picked from plate L1.3b (30.07.10) <br>
 +
- 2c, -d, -e were picked from plate L3.2b (30.07.10) <br>
 +
- 2f, -g, -h were picked from plate L2.1b (30.07.10) <br><br>
 +
DT(B0015) in pSB3c5, PCR-tube 3a-h* <br>
 +
- 3a, -b were picked from plate L1.2a (30.07.10) <br>
 +
- 3c, -d were picked from plate L2.1c (30.07.10) <br>
 +
- 3e, -f were picked from plate L2.1b (30.07.10) <br>
 +
- 3g, -h were picked from plate L2.2a (30.07.10) <br><br>
 +
̈́* On these plates were many red colonies, this might be because no extraction was done after the cutting, which would result in un-cut plasmids to be pressent. <br>

This was run on a 1% gel with a 50-2000bp ladder. The light in this picture is bad, but it does show high concentration of DNA in six of the eight ligations. The bands are positioned above 1000bp which is expected since the FlhDCmut gene with VF2-VR is 1248bp. <br>

''Date:'' August 10th <br>
 +
''Protocol:'' [https://2010.igem.org/Team:SDU-Denmark/protocols#CP1.1 CP1.1] <br>
 +
''Notes:'' The experiment was done with Taq will the purpose only was to check if  the RFP was amplificated when using the primers VR og VF2. The PRC program used was c.f. the protocol but the elongation time was 1min and 30 sec while the biobrick in the pSB3T3 plamid are 1319bp long. For the PCR i used the mini prep product from freeze tube 29. <br>
 +
''Results:''<br> [[Image:Team-SDU-Denmark-psb3T3wRFP.jpg | 300px]]<br>
 +
Unfortunately there was no band around 1400bp and therefore the amplification was not succeed. the upper band is probably the plamid.

=== Restriction digest of PUC19 and the photosensor in pKJ606 with Nde1 ===
 +
Start date: 2/08  End date: 2/08<br>
 +
''Methods:''  Restriction digest, gel electrophoresis <br><br>
 +
''Protocol:''[https://2010.igem.org/Team:SDU-Denmark/protocols#RD1.1 RD1.1] <br><br>
 +
''Experiment done by:''  LC<br><br>
 +
''Notes:'' Since all PCR attempts with VF2 and VR had failed until now, we wanted to see if there was an insert at all in the physical DNA we received. Therefore we cut PUC19 and the photosensor to compare their lengths to each other, since the photosensor should be longer than PUC19 uncut and the cut photosensor should consist of two pieces, a 900 - 1000 BP piece and a 3600 BP piece. <br>
 +
Loading order:<br>
 +
1: PUC19 uncut<br>
 +
2: PUC19 cut<br>
 +
3: Photosensor uncut<br>
 +
4: Photosensor cut<br><br>
 +
''Results:''<br>
 +
[[Image:Team-SDU-Denmark-rd38.jpg|300px]]<br>
 +
 
 +
''Analysis:''<br>
 +
We can clearly see that the photosensor uncut is longer than the uncut PUC19. We can also see multiple bands on the cut photosensor, which are the expected lengths. This indicates that the photosensor gene should be inserted between VF2 and VR, so we are still unsure why the PCR is not working.<br>
