The plates obtained from the speading of yesterday can't be used because there are not single colonies.
We have to try again, but with a stronger dilution of the bacteria or with a smaller volume of spreading.
- Resuspension of some bacteria from the glycerol stock into 1 mL of LB+antibiotic
- Dilution 10 and dilution 100
- Spreading of 100 µL of each dilution on a LB plate containing the right antibiotic
- Overnight incubation (37°C)

=> Following a mistake, the right E0430(D166) and E0432(D167) digestion, have not been purified.
So we need to repeat the same digestion experiment tomorrow morning.

Promoter characterization plasmids
Ligation
Our ligations from yesterday didn't work. The positive control for transformation worked.
Digestion
We had a problem with a gel extraction so we have to make again the digestions from yesterday
Other digestions made:

Sequencing
- We received results of our sequencing from COCHIN
- We succeed for FlgA promoter
- FlgB and flhB don't match with our expected sequences. We decided to cut our Miniprep product with other enzymes to check our sequence.
Digestion
Protocol
- D176 : pFlgB digested with ApoI
- D177 : pFlgB digested with NruI
- D178 : pFlhB digested with BstAPI

Conclusion => the sequence of pFlgB and pFlhB are not good we will tried to isolate pFlhB again.
