Sample 1.1: Concentration: 359.5ng/ul Purity: 1.83/2.20
Sample 2.1: Concentration: 304.1ng/ul Purity: 1.85/2.23
The PCR samples were run on a 1.5% gel with a 100bp-1000bp ladder. The first three samples are all positioned between 100bp and 200bp, this is the part of the gene run with FlhDCmut fv and FlhDC rev primers. The other three samples are all positioned betveen 900bp and 1000bp, this is the pcr with FlhDC fv and FlhDCmut rev primers. All samples looked okay and were pooled as sample 1.1 (light band) and sample 2.1 (heavy band)
A gel extraction of the PCR product of sample 1.1 and 2.1 were made:
The gel extraction products were used in the preceding PCRs.

Colony PCR of FlhDCmut in pSB1AK3 and pSB1C3
Date: 9/15 2010
Done By: Louise
Protocol: CP1.3
Notes: We made 8 C-PCRs with colonies transformed with pSB1AK3 and 7 C-PCRs with colonies transformed with pSB1C3 (we made 8 but due to a mishab sample 5 was not run. Taq polymerase, VF2- and VR primers were used. Only Elongation time was altered from 2 min in the protocol to 1.5 min
Results:
The picture first picture is of FlhDCmut in pSB1AK3. This shows one band at about 400bp, the double terminator. This indicates that non of the colonies had the right plasmid.
The second picture is of FlhDCmut in pSB1C3.This shows the 4 of the 7 colonies had plasmids containing the right incert (sample 1,3, 7 and 8). These samples show a band at approximately 1200bp (FlhDCmut in pSB1C3 is 1248bp). the three other samples show a band heavier than 2000bp

Control restriction digest of cPCR product of PS in pSB1C3 and pSB1AK3
Date: 09/12
Done by: LC & Maria
Methods: Restriction digest
Protocols: RD1.1[2]
Notes:
The afore mentioned samples (B, F and H of PS in pSB1C3 and A and D in pSB1AK3) were cut with EcoRI and PstI to see if it was 1) possible to cut them at all, thereby confirming the presence of biobrick prefix and suffix and 2) determining if the insert in the plasmid has the right length.
Mix for 1 RD reaction:
12 ul H2O
1 ul PstI
1 ul EcoRI
2 ul Fast digest green buffer
5 ul PCR product
Uncut PCR product and RFP were also loaded on the gel as a control.
Results: All samples pSB1C3 samples were cut as expected (to around 2000 BP), but the restriction digest of pSB1AK3 sample A and D failed, so that one will have to be repeated with sample B and C, as these only showed a cut double terminator without the PS insert.
Second control restriction digest of cPCR product of PS pSB1AK3
Date: 09/12
Done by: LC & Maria
Methods: Restriction digest
Protocols: RD1.1[3]
Since samples A and D fromt he colony PCR gave inadequate results when cut with EcoRI and PstI, we had to repeat the restriction digest with the remaining two samples that were the right length on the cPCR, sample B and C. Samples E, F and G were also cut to confirm that there were no errors in naming the samples that resulted in sample A and D not giving the expected results.
Restriction mixture:
72 ul H2O
6 ul PstI
6 ul EcoRI
12 ul Fast digest green buffer
5 ul PCR product per sample (x6)
Uncut PCR product was loaded on the gel as a control.
Results: Only sample C showed bands at the correct length (around 2180 BP), where as all other bands were at the length of a double terminator (b0015) without the photosensor insert. All samples were properly cut indicating the presence of biobrick pre- and suffix in these. Sample C will be miniprepped and sent off to sequencing.
Second round of colony PCR on PS ligated into pSB1AK3 (containing double terminator
Date: 09/12
Done by: LC & Maria
Methods: Colony PCR
Protocols: CP1.3[4]
Notes:
Since only sample C from the previous colony PCR looked right after a restriction digest we decided to run another round of colony PCR on the photosensor ligated into pSB1AK3, to find more colonys containing the right (ligated!) plamid.
The original samples A - D were also used as a template, now called I, J, K and L. Sample M to Y were new colonies.
Premix:
42,5 µl 10xTAQ Buffer
17 µl MgCl2
17 µl VF2
17 µl VR

Miniprep of PS+B0015 sample Q and pSB3T5 containing J13002
Date: 27/7
Methods: ON, Miniprep
Protocol: MP1.1
Experiment done by: LC & Maria
Notes: PS+B0015 sample Q (1) was eluded in 20 ul to get a concentration over 200 ng/ul, so we would directly be able to send it in for sequencing. All other samples were eluded in 50 ul of elution buffer.
Results: The concentrations were as followed:
PS+B0015 (1): 180 ng/ul
PS+B0015 (2): 130 ng/ul
pSB3T5+J13002 (1 and 2): 50 ng/ul
Sample Q did not fulfill DNA technologies sample specifications for sequencing we waited with sending it in, since we were expecting the results from sample C which was sent in earlier. Since those returned positive, sample Q was never sent in, since we just proceeded with sample C.
