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

The samples were run on a 1.5% gel with a 10kb ladder. The bands are positioned between 1500bp and 1200bp. FlhDCmut in pSB1C3 is 1248bp.

Photosensor

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:

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.

PCR on pKJ606 with PSfw and PSrv primers

Date: 02/09
Done by: LC
Methods: PCR
Protocols: CP1.3[2]
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:

Results: The bands that showed up were around 1750 BP, further confirming sequencing results. New primers for taking the whole gene out have been ordered.

PCR on pKJ606 with fwPS2 and rvPS2 primers

Date: 04/09

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

Retinal

Gradient PCR on ninaB (after PCR with ninaB2fw and ninaB2rv) with ninaBfw and ninaBrv

Date: 30/08
Done by: Tommy & Marie
Methods: PCR
Protocols: CP1.1[4]
Notes:
To finde the optimal anneling temperatur a gradient PCR from 60 to 75 degrees
"ninaB" was used as template and ninaB2fw and ninaB2rv was used as primers

PCR Program:

Vary small amount of the product are observed, it is pooled and gel purifid, the nanodrop shows 372,3 and 377,1 ng/uL.

Gel purification af ninaB from gradient PCR

Date: 31/08
Done by: Tommy & Marie
Methods: PCR
Protocols: CP1.1[5]
Notes:
Gel purification was preformed on the pooled product from the gradient PCR according to the protocol
After the gel purification the 2 samples was pooled and nanodroped: 7.0 ng/ul
Furthere PCR was preformed on the purifid product

Date: 1/09
Done by: Tommy & Marie
Methods: PCR
Protocols: CP1.3[6]
Notes:
PCR was run according to protocol to the following to this program
Gel purified produckt was used as template and ninaBfw and ninaBrv was used as primers
