Week 13

27th August

Visualization by electrophoresis of the amplification of 880bp end of BBa_K098995 by PCR from the 15 candidate colonies and #11. Use of a 0.8% Agarose gel. We are expecting a band at 880 bp

  • Miniprep of colonies #11 and #21
  • Plasmids of colonies #11 and #21 have been sent for sequencing


Amplification of BBa_K274100, BBa_K115017 and BBa_J61048 by PCR using the colony #11. Visualization by electrophoresis on a 1% Agarose gel for BB3 and BB4 and a 2% Agarose gel for BB2. We are expecting a band at 123 bp for BBa_K115017, 133 bp for BBa_J61048 and 3408bp for BBa_K274100.

  • Gibson assembly for the A construction (BBa_K098995+BBa_K274100+ BBa_J61048+Plasmid pSB1A2) and for the C construction (BBa_K115017 + BBa_C0051+166bp end of BBa_K098995+BBa_K274100+ BBa_J61048+Plasmid pSB1A2). Transformation of DH5αZ1 competent cell with construction A or construction C. Petri Dishes have been placed at 37°C for 1 day (construction A) or 2 days (construction C)

28th august

Digestion by AseI and NotI of the colonies #11, #21 and the linear plasmid.

  • AseI:
    • 1 restriction site in the Plasmid pSB1A2
    • 1 restriction site in the 880bp end of BBa_K098995
  • NotI:
    • 1 restriction site either side of the B construction
