When the PCR cycles were finished, 10 µL of 6X loading dye were added. The samples were then loaded (2 x 30 µL per sample) on a 1,5% agarose gel. After electrophoresis, the bands corresponding to MP 100 and MP 120 were excised and purified using the QIAquick DNA Gel Extraction Kit (QIAGEN). The elution was made in 50 µL of water. Because the intensity of the band corresponding to MP 120 was very low, we only continued with MP 100. MP 100 was digested by EcoRI & SpeI (Forward Insert) or by XbaI & PstI (D100 : Backward Insert).

==> Conclusion : for most of the samples we have enough signal to determine the concentration of the digestion to do the ligation.


For the samples we don't succeed to obtain signals, we have migrated a second gel ( gel n°7).


==> Conclusion : The gel n°7 allowed us to know the concentration of other digestion undetermined.

Attempt to excise and purify the B0034 and B0030 BioBricks

We performed PCR on the B0034 BioBrick (MP 100) and the B0030 BioBrick (MP 120) to amplify the sequence in order to have enough amount of DNA to carry out our experiments.

PCR Protocol

For each samples,

  • 1 µl dNTP
  • 10 µl Buffer Phusion 5x
  • 2,5 µl VR2 (O18)
  • 2,5 µl VF (O19)
  • 1 µl Phusion
  • 50 µl qsp H2O (33µl)

When the PCR cycles were finished, 10 µL of 6X loading dye were added. The samples were then loaded (2 x 30 µL per sample) on a 1,5% agarose gel. After electrophoresis, the bands corresponding to MP 100 and MP 120 were excised and purified using the QIAquick DNA Gel Extraction Kit (QIAGEN). The elution was made in 50 µL of water. Because the intensity of the band corresponding to MP 120 was very low, we only continued with MP 100. MP 100 was digested by EcoRI & SpeI (Forward Insert) or by XbaI & PstI (D100 : Backward Insert).

DNA Digestion

Digestion reaction (total volume : 50 µL)

  • 25 µL DNA
  • 5 µL buffer 2 (10X)
  • 2 µL enzyme 1
  • 2 µL enzyme 2
  • 0.5 µL BSA (100X)
  • 15,5 µL water

The reaction was incubated 2 hours at 37°C. The samples (2 x 30 µL per sample) were then analysed by electrophoresis.
