Logic Gates

July 2013

  • Week 4 (1-7 July)
    04/07
    Summary of all the work we have to do for the logic gates. These are the necessary genes we needed to cloned into the logic gates.
    Fro And1: rbs-luxI and rbs-Ci-ter
    For Xor1: rbs FimE ter
    For And2: reversed rbs luxI
    For Xor2: reversed rbs-RFP-ter

  • Week 6 (15-21 July)
    Amplification of fimE recombinase (rbs+fimE) from the Michigan Team.
    Minipreps, and electrophoresis checking-> good amplification.

  • Week 7 (22-28 July)
    Problem with AND1, the synthesis is not correct. We cannot go on with this gate. We planned order a new synthesis.
    Amplification of a new rbs-luxI (BBa_K516011). We realized that the first rbs –luxI we amplified was not the good one (wrong size).
    Cloning of rbs+fimE with a terminator, wrong electrophoresis profile.

    Transfer of xor2 synthesis from puc54 to pSB1C3. We did not get xor2 inside pSB1C3, but only the backbone vector.
    Insertion of reversed RFP inside AND2 (with cla1/bamH1). Electrophoresis profiles were not correct, so the insertion was not successful. It was probably a problem of restriction time.

August 2013

  • Week 8 (29-04 August)
    Cloning of rbs+fimE with a terminator. This time we succeeded.
    Amplification of the fragment rbs luxI-rbs-CI-ter for the AND1 gate.
    Insertion of rbs-FImE-ter inside the Xor1 gate. We made restriction controls with different enzymes (stu1,hindIII), but the results were not fruitful.
    We tried again to introduce RFP inside AND2, still not working.
    We succeeded to transfer Xor2 inside pSB1C3.

    Still lot of problems to insert reversed RFP inside AND2. The transformation does not work. We needed to find a solution (strataclone? Infusion?...).
    Insertion of reversed rbs luxi inside AND2. Same problem as for AND2-RFP.
    Cloning of rbs-fimE-ter into Xor1. It did not work because of a ligation problem.

    Assembly of And 1 gate extracted by PCR and rbs RFP term part
    Assembly of Xor 1 gate and rbs RFP term parts

  • Week 12 (26-31 August)

    Creation of another reversed RFP fragment but with bamH1 restriction site on each side of this DNA fragment. With this, we were able to overcome the problem of two cla1 restriction site inside XOR2. We cloned this fragment into XOR2. But it didn’t work.
    It seemed that RFP was well inserted into AND2, but after DNA sequencing analysis, we didn’t get the right fragment at the right place.
    First verification of cloning parts size by digestion by EcoRI and PstI enzymes:

    o And 1 – pSB1K3

    - And 1 fragments: about 500 bp.
    o Xor 1 - rbs RFP term – pSB1K3
    - pSB1K3 linearized: about 2200 bp.
    - Xor 1 - rbs RFP term fragments: about 1200 bp.
    o And 1 - rbs RFP term – pSB1C3
    - pSB1C3 linearized: about 2000 bp.
    - And 1 - rbs RFP term fragments: about 1200 bp.





    => Cloning parts size is confirmed.

    • Second verification of cloning parts by digestion:
    o Xor 1 - rbs RFP term digested by EcoRI and BstXI => 2 fragments: about 1007 bp and 2370 bp .
    o And 1 – rbs RFP term digested by EcoRI and BstXI => 2 fragments: about 1012 bp and 2350 bp.
    o And 1 – pSB1K3 digested by EcoRI and PsiI => 2 fragments: about 266 bp and 2440 bp.





    => Cloning parts are confirmed.
    • Third verification of cloning parts by sequencing
    => And 1 – pSB1K3, Xor 1 - rbs RFP term, And 1 – rbs RFP term constructions are confirmed
