PCR on pKJ606 with PSfw and VR primers

Date: 31/8
https://2010.igem.org/wiki/index.php?title=Team:SDU-Denmark/labnotes8&action=edit&section=3 Done by: LC
Methods: PCR
Protocols: CP1.3[1]
Notes:
Premix:
7,5 µl 10xTAQ Buffer
3 µl MgCl2
3 µl VF2
3 µl VR
1,5 µl dNTP
55,5 µl H2O
3 µl template (PS1 miniprep)
3/8 µl TAQ Polymerase

PCR Program:

Start
94  C
2 min
Denaturing
94 C
1 min
Annealing
55 C
1 min
Elongation

4 C



Results: The bands that showed up were around 2500 BP as expected from the sequencing results. This means that the designed primers have a high possibility of working, so that they will be ordered.

Results: Primers were confirmed working, the next step will be PFU pcr.

Flagella


Since the previous FlhDCmut was wrongly mutated due to incorrect mutation primers, we are now back to square one with new correct primers. The next weeks the flagella-group are working according to the following plan:
1) Miniprep of plasmids with "wrong" FlhDCmut

2) Two-step PCR to get mutatet FlhDC
3) Cut and Ligate into pSB1C3 and pSB1AK3 and transform into TOP10 cells
4) Send to sequencing
5) Characterize biobrick

Miniprep of "wrong" FlhDCmut


Done by: Louise
Date: September 3rd
Protocol: [MP1.2]
Notes:
No changes of protocol were made.
Results: Nanodrop after sample was dried down:
Sample 1: Concentration: 192ng/ul Purity: 1.96/1.90
Sample 2: Concentration: 200ng/ul Purity: 1.84/1.88


Two-step PCR of miniprep


First step: PCR of miniprep with mutation primers


Done by: Louise
Date: September 7th
Protocol: [CP1.1]
Notes:
3 x Premix 1:
114.3ul water
15ul Pfu Buffer
4.5ul dNTP
3ul MgSO4
4.5ul FlhDC fw
4.5ul FlhDCmut rev
1.2ul PFU
3ul template (miniprep)

3 x Premix 2:
114.3ul water
15ul Pfu Buffer
4.5ul dNTP
3ul MgSO4
4.5ul FlhDCmut fw
4.5ul FlhDC rev
1.2ul PFU

Results:
The PCR samples were run on a 1.5% gel with a 100bp-1000bp ladder. All samples looked okay and were pooled as sample 1.1 and sample 2.1
