Week 4: 06/09/08 - 06/13/08

  • We prepared 4 glycerol stocks taking 800 µl from 9 ml cultures containing:
BBa_B0030 (one of the two cultures) BBa_R0051 BBa_E0240
BBa_J23100-BBa_B0030
  • Miniprep for the 5 cultures.
  • We performed PCR on extracted BBa_J23100-BBa_B0030.
  • We performed electrophoresis on PCR result to check for contaminating plasmids: the plasmid was correct.
  • We sent purified BBa_J23100-BBa_B0030 to Primm for sequencing.
PCR results for BBa_J23100-BBa_B0030 ligation: plasmid length is correct
  • We performed digestion protocol to open plasmids:
BBa_B0030 (1st culture) (E-X) BBa_R0051 (S-P) BBa_E0240 (E-X)
BBa_B0030 (2nd culture) (S-P)
  • We ran a gel with these parts.
  • We performed gel extraction.
  • Antarctic Phosphatase for these 4 parts.
  • Ligation (30 µl final volume):
  1. BBa_J23100-BBa_E0240        (Pcon(E-S)-assGFP(E-X))
  2. BBa_R0051-BBa_B0030        (Plam(S-P)-RBS(X-P))
  3. BBa_B0030-BBa_E0040        (RBS(S-P)-GFP(X-P))
  4. BBa_B0030-BBa_C0051        (RBS(S-P)-cI(X-P))
  5. BBa_B0030-BBa_E1010        (RBS(S-P)-RFP(X-P))
  6. BBa_B0030-BBa_C0061        (RBS(S-P)-luxI_LVA(X-P))
  7. BBa_B0030-BBa_C0078        (RBS(S-P)-lasI(X-P))
  • We incubated ligation overnight at 16°C.



06/10/08

  • We plated the 7 ligations.



06/11/08

  • BBa_J23100-BBa_E0240 and BBa_R0051-BBa_B0030 plates showed respectively 4 and 1 colonies, while the other plates didn't show any colony.
  • We picked up one colony from the two working plates to grow 9 ml cultures of transformed bacteria overnight.
  • We also infected 9 ml of LB + suitable antibiotic with 30 µl of:
BBa_E0240 BBa_B0030 BBa_E0040 BBa_E1010
BBa_C0051 BBa_C0061 BBa_C0078
  • glycerol stocks. We incubated all the 9 ml cultures overnight at 37°C.
