RBS + TetR TetR 2,925 2,802 3,478 732
pLac + GFP GFP 3,162 3,034 3,715 964

pTetR + mCherry mCherry 3,107 2,957 3,660 887
BBa_K1140005 3-E1 2,811 --- --- 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 pSB 1C3, pSB 1A3 and pUC57 so here there is the information about the length of the part and the length in each plasmid.

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 colour after several hours at 42ᵒC. 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 500 µL at 30°C with tubes of 1.5 ml. They were left at 4°C meanwhile they were incubated.

    Set Temperature Velocity Time Live
    Black Set 42ºC 900 rpm 15 hours :(
    Blue Set 37ºC 900 rpm 21 hours :)
    Red Set 32ºC 900 rpm :)

    Time 10:25 – 9:15 = 22:50 hrs


    August 12th, 2013

    The experiment was repeated at 42°C allowing the oxygen in to the tube. It began at 2:15 pm and ended at 1:20 pm of the next day.

    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
    pCons-LacI 1326 1.6 0.62/1
    pTetR-mCherry 960 2.2 0.45/1
    pLacI-GFP 1005 2.1 0.47/1

    August 19th, 2013

    This ligation was not successful in the transformation.

    Dishes of:pTet-mCherry, pCons-LacI, pTetR, pLacI-GFP, and the 3-1E DNA were planted again.


    August 26th, 2013

    All the dishes were transformed but only the pLacGFP grew successfully.


    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 successfully 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 successful and we did digestions with EcoRI. Transformations (one tube each one): TetR, pConLac1, TetRmCherry, 3-1E, pLacGFP. *They were planted in Ampicilin dish.


    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 in Ampicilin dish.


    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, E. coli strain Top10.


    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 vector 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 Petri dishes were made, and use for transformation today.


    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 (our Gel #700!!!). After hours, we did a electrophoresis and we realised that 2 new parts were now in the pSB 1C3 vector.

    October 17th, 2013

    We started a new test in order to measure number of plasmids per cell in M1, M2 and M12.


    October 18th, 2013

    First results for number of plasmids.


    October 21th, 2013

    More results for number of plasmids.


    October 22th, 2013

    A test for measuring expression of GFP (in pUC57 and pSB1C3) was prepared in microcentrifuge tubes with LB medium and IPTG 1mM for 17 hours at 37 °C (in bacteria E. coli Top10) in thermomixer.

    We still have problems with expression of mCherry, so we did new cultures with stored (red) M1, M2 and M12 in order.


    October 23th, 2013

    We used fluorometer to measure expression of GFP, but any fluorescence was detected, so new microcentrifuge tubes with GFP construction were prepared at same conditions of last day.

    The cultures of M1, M2, M11 and M12 were red and presented fluorescence, so we did minipreparation and culture again them in new tubes. With the DNA that was obtained, a digestion with EcoRI and PstI was done and a new ligation.


    October 24th, 2013

    Again, any fluorescence was detected for GFP cultures. New microcentrifuge tubes with GFP construction were prepared with IPTG 0.5 mM.

    A new transformation was done, using new mCherry and latest TetR and LacI ligations.

    Cultures of M11 and M12 grew, but any with M1 and M2. We did minipreparation and the DNA was measured in nanodrop.


    October 25th, 2013

    Residual fluorescence was detected for GFP cultures.

    We inoculated the colonies obtained from the transformations.


    October 26th, 2013

    Cultures of mCherry grew, but the others did not. We did minipreparation of that tubes and digested them with EcoRI, PstI and HinfI. The results can be seen on gel # 709 (EcoRI/PstI) and 710 (HinfI). Probably, we have multiple clones with mCherry in pSB1C3.

    New ligations of TetR, LacI and GFP with pSB1C3 were done and a transformation was made in a new competent stock, Top10 strain.

    Figure 6. Electrophoresis gel (710) with the HinfI clones digestion, Lambda-PstI as marker.


    October 28th, 2013

    We did minipreparation and digested them with HinfI to identify more positive clones. As a result we get at the most two positive clones, one for pSB-mCherry and one for pSB-GFP
