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

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.

All of the PCR product was loaded onto a 1.5 agarose extraction gel. Gene ruler DNA ladder mix was used ad marker.
Results:
Analysis:
No bands were visible in the gel, indicating that the PCR reaction had been unsuccessfull. This could be due to the low elongation time, wherefore another PCR reaction with a longer elongation time was carried out.

Notes:
The compotent cells and transformation was carried out according to protocol. Cells transformed with ligations of PS in pSB1AK3 was plated on kanamycine plates.
Results:
the controle plates were okay, and there was many colonies on plates with cells transformed with ligations of pSB1C3 and PS. There was 10-20 colonies on the plates with cells transformed with ligation of PS and pSB1AK3.
