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

    All DNA fragments seemed to be correctly amplified.

  • PCR products were purified thanks to Macherey Nagel PCR Clean up Kit.

  • The DNA concentration of PCR products was tested thanks to the Nanodrop. Results are presented below.

    # Concentration of DNA (ng/µL)
    2 52.28
    3 44.86
    6 49.93
    8 73.38
    9 76.77
    10 57.00
    11 39.87
    12 50.88
    13 62.42
  • PCR products number 6, 8 and 9 were stocked at -20°C whereas PCR products number 2, 3, 10, 11, 12 and 13 were used to realize SLIC protocol. This protocol permits to assemble all parts of SerA and Mesh1 genes with their directed mutation. The destination plasmid DNA used is the backbone pSB1A3 linearized plasmid. DH5α supercompetent bacteria were transformed with SLIC products and spread over Amp dish.
  • Several plasmids were purified thanks to Macherey Nagel MiniPrep Kit :
    • Brick 200 (3)
    • Brick 200 (4)
    • Brick 200 (5)
    • Brick 200 (6)
  • The efficiency of the purification was tested thanks to agarose gel electrophoresis. Results are presented following.
    Brick 200 (6) well did not present any DNA fragment. Other wells contain one or two fragments of DNA, so Brick 200 (3), 200 (4) and 200 (5) were successfully purified.

  • Several control PCR were realized to verify if SLIC worked. Taq polymerase was used. Three clones of each SLIC were tested. They were also pricked up on Amp dish.

    # DNA Template Primers Numbers Primers Names Weight of amplified DNA
    S1 Clone 1 of SLIC SerA 5 - 6 serA_PrefRFC10RBS_up

    S7 Clone 7 of SLIC Mesh1 with STOP 24 - 26 Mesh_1_RFC10-RBS_up
    Mesh_1_2_stop_SufRFC23_down    		 582 bp
    S8 Clone 8 of SLIC Mesh1 with STOP 24 - 26 Mesh_1_RFC10-RBS_up

    Mesh_1_2_stop_SufRFC23_down    		 582 bp

  • Several DNA fragments were amplified thanks to iGEM PCR protocol (Q5 polymerase).

    # DNA Template Primers Numbers Primers Names Weight of amplified DNA
    1 pKD4 plasmid 1 - 2 sdaCsdaB_mut_pKD4_up
    sdaCsdaB_ mut_pKD4_down    		 1032 bp
    4 pKD4 plasmid 3 - 4 cheA_mut_pKD4_up
    cheA_mut_pKD4_down    		 1032 bp
    5 Genomic DNA of W3110 9 - 14 cheA_PrefRFC23_up
    cheA_mut_T1290C_down    		 1032 bp
    7 Genomic DNA of W3110 15 - 17 relA_mut_C1366G_up
    relA_RFC10-RBS_up    		 579 bp
    PCR product 1 and 4 were correctly amplified. Thus, they were purified thanks to Macherey Nagel PCR Clean up Kit. PCR product 5 and 7 seemed to be compound with too many different DNA fragments. That's why, a new amplification by PCR was made overnight (iGEM PCR protocol Q5 polymerase).
  • Realization of "Day 2" of lambda red pKOBEG protocol. W3110 with active recombinase was electroporated by PCR product 1 (sdaCsdaB) and 4 (cheA). Transformed bacteria were spread over a Kan dish.

  • The efficiency of the purification of PCR product number S1 to S9 was tested thanks to agarose gel electrophoresis. At the same time, the efficiency of the amplification of the beginning sequences of CheA and RelA (PCR product 5 and 7) was tested thanks to agarose gel electrophoresis. Results are presented below.

    PCR products 5 and 7 were good for SLIC. Clone 1 and 2 (serA), clone 4 and 6 (Mesh1 without STOP) and clone 7 and 8 (Mesh1 with STOP) were put in culture in LB with Amp.
  • The DNA concentration of PCR products 5 and 7 was tested thanks to the Nanodrop. Results are presented below.
    # Concentration of DNA (ng/µL)
    5 29.78
    7 85.51
  • PCR products number 5, 6, 7, 8 and 9 were used to realize SLIC protocol. This protocol permits to assemble all parts of CheA (5 and 6) and RelA (7 and 8 without STOP, 7 and 9 with STOP) genes with their directed mutation. The destination plasmid DNA used is the backbone pSB1A3 linearized plasmid. DH5α supercompetent bacteria were transformed with SLIC products and spread over Amp dish.
  • SLIC assembly of RelA was a success but SLIC assembly of CheA failed. That's why, a new SLIC assembly of CheA with PCR products 5 and 6 was made. The destination plasmid DNA used is the backbone pSB1A3 linearized plasmid. DH5α supercompetent bacteria were transformed with SLIC products and spread over Amp dish.
  • Realization of "Day 2" of lambda red pKOBEG protocol a second time. PCR product 1 and 4 were purified a second time. The efficiency of the purification was tested thanks to agarose gel electrophoresis. Results are presented below. W3110 with active recombinase was electroporated by PCR product 1 (sdaCsdaB) and 4 (cheA). Transformed bacteria were spread over a Kan dish.

  • Several control PCR were realized to verify whether RelA SLIC worked. Taq polymerase was used. Three clones of each SLIC were tested. They were also pricked up on Amp dish.

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

    PCR products 1 and 4 were correctly amplified. Thus, they were purified thanks to Macherey Nagel PCR Clean up Kit. Transplanting of S22 to S27 failed, those clones were gave up.

    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.

  • 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.

  • 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.

  • 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.
