    The efficiency of the amplification was tested thanks to agarose gel electrophoresis. Results are presented below.

    Neither cusR promoter no stability label clone seemed to present the right construction, these cloning had to be remade. Nevertheless, every SH3pep and cusR box clones seemed to be correctly amplified. Clones 1 and 4 of cusR box (CB1 and CB4) and clones 4 and 10 of SH3pep (SP4 and SP10) were chosen to go on brick construction.

    Clones 42, 43, 44, 47 and 48 of RFP and GFP without STOP codon seemed to be correctly amplified. Only clones 1,2 and 3 of cusR-L-LZa seemed to present the right construction. Clones 42, 43, 47 and 48 of RFP and GFP without STOP codon (RFP42, RFP43, GFP47 and GFP48) and clones 2 and 3 of cusR-L-LZa (CZ2 and CZ3) were chosen to go on brick construction.

    No (SH3)4 clone seemed to present the right construction, this cloning had to be remade. Only clones 3 and 4 of Mesh1 without STOP codon (MSS3 and MSS4) seemed to present the right construction, these clones were chosen to go on brick construction. No clone of Mesh1 with STOP codon was correctly amplified, other clones were going to be tested by PCR.

    Only clone 5 of SLIC CheA (CA5), clones 2 and 5 of RelA with STOP codon (RA2 and RA5) and clones 4 and 5 of RelA without STOP codon (RAS4 and RAS5) seemed to present the right construction. Thus, only these clones were chosen to go on brick construction.

    Clone 1 was the only clone of SLIC SerA correctly amplified. SA1 was chosen to go on brick construction.

  • TG1 competent cells were prepared to substitute DH5 alpha that grows up too slowly.

  • PiGEM_02.27 (pSB1A2, BBa_J04450) was digested with XbaI, SpeI and PstI to be used for stability label cloning. Stability labels were assembled a third time by annealing.

  • Plasmids containing the stability labels 27/28 K1051206 clone St8, the stability labels 29/30 K1051207 clones St16, 17, 19, 20 and 21 and the stability labels 31/32 K1051208 clones St24, 26, 27, 28, 29 and 33 were digested by XbaI to determine whether they presented the expected construction.

    The efficiency of the digestion was tested thanks to agarose gel electrophoresis. Results are presented below.

    The weight of digested fragment were too heavy. It was impossible that only one stability label was inserted in one iGEM plasmid. Certainly, several stability labels were associated in a same plasmid. The cloning of stability label must have be remade with new ratios of stability label and plasmid.

  • PiGEM_02.27 (pSB1A2, BBa_J04450) was digested with EcoRI and PstI to be used for PCR product 239 cloning. PCR product 239 (cusR promoter) was digested by EcoRI and PstI. Then, PCR product 239 was leagued in pSB1A2 digested. Tg1 competent cells were transformed with these ligation products and spread on Amp dish.

  • Bricks 200 and 202 were built again by changing destination plasmid. 3A protocol was implemented to assemble the upstream part with downstream part and with the destination plasmid. Tg1 competent cells were transformed with these ligation products and spread on Kan or Cm dish. The cloning plan is presented below.

    The efficiency of the amplification was tested thanks to agarose gel electrophoresis. Results are presented below.

    All clones seemed to present the right construction. Clones 200(3), 200(5), 202(1) and 202(3) were chosen to go on brick construction.

  • Several plasmids were purified thanks to Macherey Nagel MiniPrep Kit :

    • CusR promoter clones 2 and 8 (PCU2 and PCU8) ⇒ PiGEM_02.61 and PiGEM_02.62
  • We prepare seven starter of W3110 sdaBC- KanR strain with Kan50.

  • Sequencing results of plasmids PiGEM_02.33, PiGEM_02.34, PiGEM_02.35, PiGEM_02.36, PiGEM_02.37, PiGEM_02.38, PiGEM_02.39, PiGEM_02.40, PiGEM_02.41, PiGEM_02.42, PiGEM_02.43, PiGEM_02.44, PiGEM_02.45, PiGEM_02.46, PiGEM_02.47, PiGEM_02.48 were received. Thus, clones CB1, SP10, CZ3, CA38, RA2, MS8, MSS4, GFP47, RFP43, RAS5 and PCU2 had the right construction. Because no clone of SLIC SerA was correct, several control PCR were realized to verify whether other clones of SLIC SerA had the right construction. Taq polymerase was used.

    The efficiency of the amplification was tested thanks to agarose gel electrophoresis. Results are presented below.

    There were bands at the right molecular weight but clone SA1 got the same band (AS36). Nevertheless, this clone did not have the right construction (bad sequencing result). Thus, SerA was going to be assembled again by another protocol (Gibson protocol).

  • Plasmids containing the flag (Fl1 and Fl3) were digested by XbaI to determine whether they presented the expected construction.

    The efficiency of the digestion was tested thanks to agarose gel electrophoresis. Results are presented below.

    Clone Fl1 and Fl3 seemed to present the expected construction.

  • We realize day 7 of Lambda Red protocol on W3110 sdaBC- pCP20 strain.

  • Several plasmids were purified thanks to Macherey Nagel MiniPrep Kit :

    • Bricks 200 (3) and 200 (5) ⇒ PiGEM_02.65 and PiGEM_02.66
    • Bricks 202 (1) and 202 (3) ⇒ PiGEM_02.67 and PiGEM_02.68
  • Unfortunately, colonies careering bricks 200 and 202 were respectively red and green while constructions of these bricks were not supposed to contain any promoter. Thus, PiGEM_02.65, PiGEM_02.66, PiGEM_02.67 and PiGEM_02.68 were sent in order to be sequenced. In the mean time, RFP and GFP were assembled to another RBS to test whether the RBS B0034 was correct. The cloning plan is presented below.

    Part Number Description Upstream Part Downstream Part Destination Plasmid
    A RBS B0030 with RFP with stop codon PiGEM_01.05 Cm PiGEM_01.04 Cm PiGEM_01.13 Cm
    B RBS B0030 with GFP with stop codon PiGEM_01.05 Cm PiGEM_02.03 Cm PiGEM_01.13 Cm
  • Several control PCR were realized to verify whether stability labels cloning with different ratios worked. Taq polymerase was used.

    The efficiency of the amplification was tested thanks to agarose gel electrophoresis. Results are presented below.

    Clone Fl1 and Fl3 seemed to present the expected construction.

    Unfortunately, there was not any expected result. Stability labels constructions did not success once again. New oligonucleotides were going to be ordered to try a new protocol.

  • We realize day 8 of Lambda Red protocol on W3110 sdaBC- strain.

Week 9 : 08/25/2014 ➡ 08/31/2014

  • RelA (RA2) and Mesh1 (MS8) were assembled with a Lac promoter and the reference RBS (BBa_B0034) to characterize parts. 3A protocol was implemented to assemble the upstream part with downstream part and with the destination plasmid. Tg1 competent cells were transformed with these ligation products and spread on Kan glucose dish to prevent RelA and Mesh1 expression that could slow cells growth. The cloning plan is presented below.

    Part Number Description Upstream Part Downstream Part Destination Plasmid
    x Promoter with RBS and RelA with stop codon PiGEM_01.08 Cm PiGEM_02.41 Amp PiGEM_02.28 Kan
    y Promoter with RBS and Mesh1 with stop codon PiGEM_01.08 Cm PiGEM_02.48 Amp PiGEM_02.28 Kan
  • We realize day 9 of Lambda Red protocol on W3110 sdaBC- strain, and day 2 of Lambda Red protocol on W3110 sdaBC- strain with #294 PCR product

  • Sequencing results of plasmids PiGEM_02.65, PiGEM_02.66, PiGEM_02.67 and PiGEM_02.68 were received. PiGEM_02.67 and PiGEM_02.68 had the right construction but PiGEM_02.65 and PiGEM_02.66 had not. Thus, RBS BBa_B0034 was correct. There was no reason for the colonies containing bricks 200 and 202 to be green or red without promoter sequence.

  • Several control PCR were realized to verify whether RelA and Mesh1 cloning with their promoter and RBS worked. (SH3)2 new construction were also tested. Taq polymerase was used.

    The efficiency of the amplification was tested thanks to agarose gel electrophoresis. Results are presented below.

    Some clones seemed to present the right construction. Clones 1 and 2 of BBa_J04500 with RelA were chosen to continue the part characterization. In the mean time, to go on the part characterization, clones 2, 5, 6 and 8 of BBa_J04500 with Mesh1 were selected. Clones 2 and 5 were going to be used as negative controls (empty plasmids) and clones 6 and 8 were going to be used as functional parts.

  • We realize day 3 of Lambda Red protocol on W3110 sdaBC- strain CheA- KanR.

  • Check the construction 200(2) (RBS B0034 + RFP E1010) by digestion.

    7µL E1010 (control) (500ng)
    36µL H2O
    5µ NEB Buffer 2.1
    1µL XbaI
    1µL EcoRI


    2µL 200(2) (500ng)
    36µL H2O
    5µ NEB Buffer 2.1
    1µL XbaI

  • Two new cells strain were selected to characterize RelA and Mesh1 parts. The first one is EB425 (ppGpp°) which does not produce ppGpp any more. The second one is EB544 (ppGpp++) which produces ppGpp with greater stability. These Escherichia coli strains were used to prepare two samples of competent cells. EB425 were going to be complemented by RelA whereas EB544 were going to be complemented by Mesh1.

  • We realize day 4 of Lambda Red protocol on W3110 sdaBC- strain CheA- KanR. strain.

  • PCR2: Second PCR round to amplification of serA from the SOE product (26-08-14) with primers 5 and 6, using the iGEM PCR protocol with Q5 polymerase. The temperature of annealing is 60°C

    Result: the amplification of serA is good. Clean-up of serA (PCR2) and elution with 45µL of water.

  • Several plasmids were purified thanks to Macherey Nagel MiniPrep Kit :

    • J04500 with RelA (RA2) Clones 1 and 2 ⇒ PiGEM_02.69 and PiGEM_02.70
    • J04500 Mesh1 (MS8) Clones 2 and 5 ⇒ PiGEM_02.71 and PiGEM_02.72
    • Empty plasmids Clones 6 and 8 ⇒ PiGEM_02.73 and PiGEM_02.74
  • To characterize RelA and Mesh1 parts, growth rate would be evaluated. At first, EB425 competent cells (ppGpp°) were transformed with PiGEM_02.05 (pT18 RelA, positive control), with PiGEM_02.74 (empty plasmid, negative control) and with PiGEM_02.69 and PiGEM_02.70 (pLac RelA, built part). Then, EB544 competent cells (ppGpp++) were transformed with PiGEM_02.06 (pBAD Mesh1, positive control), with PiGEM_02.74 (empty plasmid, negative control) and with PiGEM_02.71 and PiGEM_02.72 (pLac Mesh1, built part). Cells were spread over Kan glucose dish to prevent RelA and Mesh1 expression. Some colonies were going to be spread later on selective dish to observe any difference in growth rate.

  • We realize day 5 of Lambda Red protocol on W3110 sdaBC- CheA- KanR strain.
