Week 8: 07/7/08 - 07/12/08

07/7/08

  • Colony PCR (5 colonies for each plate) for:
    • BBa_J23100-BBa_B0030-BBa_C0012 (for the second time, we hoped to find true positive colonies)
    • BBa_J23100-BBa_B0030-BBa_I15010 (for the second time, we hoped to find true positive colonies)
    • BBa_B0030-BBa_E0040-BBa_B1006
    • BBa_B0030-BBa_C0051-BBa_B0030
    • BBa_B0030-BBa_E1010-BBa_B1006
Colony PCR: Marker (1), empty (2) BBa_J23100-BBa_B0030-BBa_C0012, BBa_J23100-BBa_B0030-BBa_I15010, BBa_B0030-BBa_E0040-BBa_B1006, BBa_B0030-BBa_C0051-BBa_B0030, BBa_B0030-BBa_E1010-BBa_B1006, blank
  • Gel results:
    • No true positives for BBa_J23100-BBa_B0030-BBa_C0012
    • No true positives for BBa_J23100-BBa_B0030-BBa_I15010
    • Non pure true positives for BBa_B0030-BBa_E0040-BBa_B1006
    • Pure true positives for BBa_B0030-BBa_C0051-BBa_B0030
    • Non pure true positives for BBa_B0030-BBa_E1010-BBa_B1006
  • We chose to keep the first colony for all the 3 working ligation plates.
  • NOTE: BBa_B0030-BBa_E0040-BBa_B1006 and BBa_B0030-BBa_E1010-BBa_B1006 are final parts; we decided to sequence these 2 parts even if gel showed a weak contamination: sequencing results will tell us if there are false positive plasmids in those colonies or if the contamination was only a PCR contamination.
  • We infected 9 ml LB + suitable antibiotic with 30 µl of these glycerol stocks:
BBa_B0030 BBa_I15010 BBa_B0030-BBa_E0040-BBa_B1006 (1) BBa_B0030-BBa_E1010-BBa_B1006 (1)
BBa_C0012 BBa_R0062 BBa_B0030-BBa_C0051-BBa_B0030 BBa_J23100-BBa_B0030
  • We incubated the 8 cultures at 37°C, 220 rpm overnight.
  • Tomorrow we will be ready to perform NINE LIGATIONS...(@_@!)



07/8/08

  • We received sequencing results for BBa_B0030-BBa_C0078: sequence showed an extra DNA fragment between BBa_C0078 and Suffix...We decided to ignore it because there was a stop codon before that fragment.
  • Glycerol stocks for:
BBa_B0030 BBa_I15010 BBa_B0030-BBa_E0040-BBa_B1006 (1) BBa_B0030-BBa_E1010-BBa_B1006 (1)
BBa_C0012 BBa_R0062 BBa_B0030-BBa_C0051-BBa_B0030 BBa_J23100-BBa_B0030
  • Miniprep for these parts.
  • Plasmid digestion for:
BBa_B0030 (S-P) BBa_I15010 (X-P) BBa_B0030-BBa_E0040-BBa_B1006 (1) (E-X) BBa_B0030-BBa_E1010-BBa_B1006 (1) (E-X)
BBa_C0012 (X-P) BBa_R0062 (E-X) BBa_B0030-BBa_C0051-BBa_B0030 (S-P) BBa_J23100-BBa_B0030 (E-S)

  • Gel run/cut/gel extraction for:
BBa_I15010 (X-P) BBa_J23100-BBa_B0030 (E-S) BBa_J23100-BBa_B0030-BBa_C0040 (E-S)
BBa_C0012 (X-P) BBa_R0051-BBa_B0030-BBa_C0062 (E-S) BBa_B0030-BBa_C0061-BBa_B1006 (E-S)
  • DNA precipitation with sodium acetate for:
BBa_B0030 (S-P) BBa_B0030-BBa_E0040-BBa_B1006 (1) (E-X) BBa_B0030-BBa_E1010-BBa_B1006 (1) (E-X)
BBa_R0062 (E-X) BBa_B0030-BBa_C0051-BBa_B0030 (S-P)
  • (We already had BBa_I15009(X-P) and BBa_B1006(E-X))
  • Ligations:
  1. BBa_B0030-BBa_I15009
  2. BBa_J23100-BBa_B0030-BBa_C0040-BBa_B1006
  3. BBa_R0051-BBa_B0030-BBa_C0062-BBa_B1006

  7. BBa_J23100-BBa_B0030-BBa_I15010 (again)
  8. BBa_J23100-BBa_B0030-BBa_E0040-BBa_B1006 (to test the part)
  9. BBa_J23100-BBa_B0030-BBa_E1010-BBa_B1006 (to test the part)
  • We incubated ligations at 16°C overnight.
  • We infected 9 ml LB + Amp with 30 µl of BBa_B1006 and BBa_B0030-BBa_C0078 glycerol stocks. We incubated the 2 cultures at 37°C, 220 rpm ovenight.



07/9/08

  • Glycerol stocks for BBa_B1006 and BBa_B0030-BBa_C0078.
  • Miniprep for BBa_B1006 and BBa_B0030-BBa_C0078.
