Mutation of FT by Sato
FT gene has two BioBrick restriction enzyme sites, EcoR1 and Pst1 which is next to each other.
So we tried to delete both at once by using two primers with mutation.

Cells were stored on ice for 30min.
After 42°C 60sec heat shock, cells were stored on ice for 2min.
Then cells were precultureed at 37°C for 1hr, plated to Kanamycin plate.

Liquid culture of FT 37°C, overnight

Miniprep of FT : by Sato, Takeuchi
The concentrarion was 81.5ng/uL
Restriction digestion and Electrophoresis : by Sato
To check wheter mutation was succeed, we did restriction enzyme digestion.

37°C 2h incubate
We did electrophoresis of three FT plasmids, non-cutted, EcoR1 cutted, Pst1 cutted.
However, we couldn't get any bands (data not shown.)
Liquid culture of FT (4mL)
August 15
Miniprep of FT : by Sato, Takeuchi, Hyungcheol
We couldn't get enough concentration of plasmids.
Electrophoresis : by Sato
We retried electrophoresis of three samples same as yesterday.
However, we couldn't get any bands as well.

| FT | - | 2 | 2 | 18 | 22 | LB (Kan+) | × |
We found that mutation of FT was not successful.
August 20
We decided to do PCR using FT specific primers before mutation.
PCR of FT : by Sato
| 10xBufer | dNTPs | MgSO4 | primer fwd | primer rev | template | polymerase | MilliQ | Total |
|---|---|---|---|---|---|---|---|---|
| 5 | 5 | 3 | 1 | 1 | 1(130ng/µL) | 1(KOD plus neo) | 33 | 50 |
94°C 2min, (98°C 10sec, 68°C 15sec)x30cycles, 4°C Hold
After the ethanol precipitation, we diluted in 30µL of MilliQ.
The concentration was 203ng/µL.

37°C, 5h incubate
After the ethanol precipitation, we diluted in 30µL of MilliQ.
The concentration was 54,9ng/µL.

Golden Gate Assembly method This method helps us to constract some genes quickly and we can design the order of constractions. We are trying to construct a gene cycle composed of 6 genes( pSB1A3, lacI, GFP, RFP, GFP, DT). After this experiment is confirmed to work, we will so some experiment to check how the numbers of promorters influences the strength of transcription.
