Reference Data
| Part Name | Part Short name | In pSB1A3 (bp) | In pSB1C3 (bp) | In PUC57 (bp) | Part size (bp) |
|---|---|---|---|---|---|
| RBS + TetR | TetR | 2925 | 2802 | 3478 | 732 |
| pLac + GFP | GFP | 3162 | 3034 | 3715 | 964 |
| pCons LacI | LacI | 3483 | 3352 | 4036 | 1,282 |
| pTetR + mCherry | mCherry | 3107 | 2957 | 3660 | 887 |
| BBa_K1140005 | 3-E1 | 2811 | --- | --- | 935 |
This table works as a reference of the parts that were used in the laboratory and in the diary. We have a short name for each part so for example, if a diary entry says "TetR" we mean the complete part "RBS + TetR". Another important aspect is that we were working with the plasmids pSB1C3, pSB1A3 and PUC57 so here there is the information about the length of the part and the length in each plasmid.
August 4th, 2013
Today we prepared solutions in order to start working on the lab the following day. The solutions will be required for the MiniPrep, Transformation. We also prepared aliquots, mQ water with RNAse, etc.
August 5th, 2013
Today we started with the transformations of the synthetic DNAs that just arrived.
August 6th, 2013
We inoculated the colonies obtained from the transformations.
August 7th, 2013
This day we did Minipreparation of DNA. The parts that were obtained were the following: LacI, GFP, mCherry, TetR and 3-1E
August 8th, 2013
Test of mCherry with Thermo-mixer-Cualitative experiment
20 Colonies of the dish with pTet-R-mCherry were planted in 0.5 mL of Agar with Kanamycin in order to observe the red color after several hours at 42ᵒ C. The experiment was performed following these parameters.
| Start | End | Hours | |
|---|---|---|---|
| 37ºC | 2:50 pm | 7:02 pm | 4 hr 12 min |
| 42ºC | 7:05 pm | 10:35 am | 15 hr 40 min |
Most tubes shown development seeing them on the light but there was no color shown.
August 10th, 2013
20 tubes with mCherry were put in the shaker with 2 controls with CDS (with oxygen everyone), following these parameters:- Temperature: 37ᵒC
- Revolutions: 900 rpm
- Start: 11:35 am -> 9:00 am (Time 21: 35 hours)
The tubes show mCherry expression, some more intense than others.The experiment was repeated at 30°C OVERNIGHT with a volume of 500µL at 30°C with tubes of 1.5ml. They were left at 4°C meanwhile they were incubated.
| Set | Temperature | Velocity | Time | Live |
|---|---|---|---|---|
| Black Set | 42ºC | 900rpm | 15 hours | :( |
| Blue Set | 37ºC | 900rpm | 21 hours | :) |
| Red Set | 32ºC | 900rpm | :) |
Time 10:25 – 9:15 = 22:50 hrs
August 12th, 2013
The experiment was repeated at 42°C with oxygen. It began at 2:15 pm and ended at 1:20 pm

| DNA | 1x | 5x |
|---|---|---|
| DNA | 2µL | |
| EcoRI | 0.3µL | 1.5µL |
| PstI | 0.3µL | 1.5µL |
| Buffer O | 1µL | 5µL |
| 10µL | 50µL |
August 18th, 2013
there where no colonies present from the previous day.
Ligation with a 1:1 ratio DNA:Vector. Is was performed with the following parameters:
| Size (bp) | Vector | DNA:Vector | |
|---|---|---|---|
| pTetR | 768 | 2.8 | 0.33/1 |
| pConsLac1 | 1326 | 1.6 | 0.62/1 |
| pTetRmCherry | 960 | 2.2 | 0.45/1 |
| pLac1GFP | 1005 | 2.1 | 0.47/1 |
August 19th, 2013
This ligation was not sucessful in the transformation.
Dishes of:PTetmCherry, PConsLac, TetR, PLacGFP, 3-1E were planted again.
August 26th, 2013
All the dishes were transformed but only the PLacGFP grew succesfully.
August 28th, 2013
Today we picked up colonies from the dishes from the previous day. We also prepared new competent cells.
August 29th, 2013
All the dishes were succesfully transformed and we planted in petri dishes. We got colonies of all the parts, they grew in the test tubes and miniPrep was done.
August 30th, 2013
The MiniPrep was succesful and we did digestions with EcorI. Transformations (one tube each one): TetR, pConLac1, TetRmCherry, 3-1E, pLacGFP. *They were planted with Ampicilin.
Figure 3. Electrophoresis gel from the August 30 miniPreps
August 31th, 2013
MiniPrep and digestions from the ones of 08/30/2013. We didn't obtained any construction.
Transformations (one tube each one): TetR, pConLac1, TetRmCherry, 3-1E, pLacGFP
*They were planted with Ampicilin.
September 11th, 2013
Digestions with EcoRI and PstI and Ligations
September 12th, 2013
We didn't obtained any part so we started again transforming them one more time.
September 13th, 2013
There were no results presented so we transformed again.
September 14th, 2013
We got no results in the construction desired.
September 19th, 2013
Quantification with the Nanodrop of the previous samples
| Ng/µL | 260/280 | |
|---|---|---|
| pSB1C3 | 1293.4 | 1.99 |
| GFP | 133.5 | 1.84 |
| TetR | 119.6 | 1.78 |
| tRFP | 104.3 | 1.74 |
| pConsLac | 130.5 | 1.59 |
September 20th, 2013
We prepared new calcium competent cells.
September 23th, 2013
We did the transformations again for all the parts.
September 24th, 2013
Again there where no results.
Note:The constructions with the pSB1A3 and pSB1C3 showed no results but the controls with PUC were fine and did work in our experiments.
October 9th, 2013
New Digestions with EcoRI and PstI.
October 10th, 2013
New ligations were done
October 11th, 2013
New dishes were transformed and plated.
October 13th, 2013
We inoculated the colonies obtained from the transformations.
October 14th, 2013
We did minipreparation of DNA. After, the DNA was digested with EcoRI, PstI and HinfI for an enzymatic analysis. After hours, we did a electrophoresis and we realized that a new part was constructed.
October 14th, 2013
We did minipreparation of DNA. After, the DNA was digested with EcoRI, PstI and HinfI for an enzymatic analysis.
Stability
For the stability experiments the tests were performed from September 14 to 20. The protocols are in the section of Safety. Click here
For the fluorescence experiments the tests were performed from September 10 to 27. The protocols are in the section of Wetlab. Click here
