by Romain
Strains used: E. coli MG1655Z1 and E. coli MG1655, and oligonucleotides used: FTR-Apra-F and FTR-Apra-R.
Protocol
Add into a PCR tube the following:
| Component | For a total volume of 50μl |
|---|---|
| H2O | 27.25μl |
| Green GoTaq buffer 5X | 10μl |
| dNTPs | 1μl |
| FTR-Apra-F | 2μl |
| FTR-Apra-R | 2μl |
| DMSO | 1.5μl |
| MgCl2 | 4μl |
| Bacterial culture | 2μl |
| Green GoTaq enzyme | 0.25μl |
Tube was placed in PCR machine with the following parameters.
| Cycle step | Temperature | Time | Cycle |
|---|---|---|---|
|
Initial denaturation |
95°C |
5 min |

| Denaturation | 95°C | 30 s | 30 |
| Annealing | 60°C | 30 s | 30 |
| Extension | 72°C | 2 min | 30 |
| Final extension | 72°C | 5 min | 1 |
| Final extension | 12°C | hold | 1 |
The different bacterial cultures in each tubes:
- Tube 1: MG1655Z1 10I
- Tube 2: MG1655 100II
- Tube 3: MG1655 50I
- Tube 4: MG1655 100I
- Tube 5: MG1655Z1 10II
- Tube 6: MG1655 50II
- Tube 7: MG1655Z1 10I positive control with plasmid
Results of the PCR: The electrophoresis revealed nothing
New PCR with different enyme.
Strains used: MG1655 and MG1655Z1, and oligonucleotides used: FTR-Apra-F and FTR-Apra-R.

E - Salicylate Inducible Suppressing System
Digestion
by Fabio
After the experiments done the 28th July, we are sure to manipulate the right plasmid from both BioBricks and also that we have a good concentration of them. Now it's time to start the [http://parts.igem.org/Help:Assembly/3A_Assembly Assembly procedure] in order to concatenate both BioBricks.
- BioBrick BBa_J61051 (Salicylate promoter + NahR)
- BioBrick BBa_K228001 (RNA suppressor)
Protocol
Electrophoresis
by Fabio
Results:
First process to verify the digestion
we are sure that we have the right BioBricks fragments and in a good concentration
Second one to separate both parts (only with J61051).
