Restriction Digest of Gel Extracted FlhDCmut, pSB1C3 and pSB1AK3

Date: 9/12 2010
Done By: Sheila
Protocol: RD1.1
Notes: The restriction digests are made in preperation for two different ligations, the first is the ligation of FlhDCmut into the submission backbone; pSB1C3. The second is the the ligation of FlhDCmut into pSB1AK3. Different restriction enzymes were used in, as shown in the following tables

Taq gradient PCR of pKJ606 with PS primers

Date: 9/7 2010
Done By: Maria and Lc
Protocol: CP1.3
Notes:
A gradient PCR was carried out to determine the appropiate annealing temperature of the new PS primers. PCR tubes were marked PSII A-H.

Premix x 9

Taq buffer (10x)	22.5uL
MgCl2	9uL
PSII fw primer	9uL
PSII rv primer	9uL
dNTP mix	4.5uL
H20	158.5uL
Taq polymerase	1uL

miniprep of pKJ606 was used as template. 1uL was distrubuted into each tube.
PCR program:

start	95C	2min
denaturating	95C	1min
annealing	se additional table	1min
elongation	72C	2min
go to	2	rep.29x
end	72C	5min
hold	4C

Anealing temperatures:

56.5C

58.3C

60.7C

63.3C

66C

68.6C

71C

73C

PCR product was loaded onto a 1.5 agarose gel. gene ruler DNA ladder mix (red) was used as marker.

Results:

Analysis:
Only very weak bands was observed at app. 2000 bp, and very strong bands were observed at app. 4000 bp, indicating that too much template was used in the PCR. An additional PCR was carried out using diluted miniprep as template.
