DNA ExtractionResults of the extraction : Electrophoresisconditions of electrophoresis:
LigationProtocolFor each samples,
List of ligations
Purification of the B0034 and B0030 BioBricksWe 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 the following of our experiments. PCR ProtocolFor each samples,
Electrophoresis - PurificationWhen the PCR cycles were finished,
Because the intensity of the band corresponding to MP 120 was very low, we only continued with MP 100.
DNA DigestionMP 100 was digested by EcoRI & SpeI (Forward Insert) or by XbaI & PstI (D100 : Backward Insert) Digestion reaction (total volume : 50 µL)
Electrophoresis
The sequence of MP 100 (B0034) digested by EcoRI & SpeI (35 bp) or XbaI & PstI (34 bp) was too short and we didn't manage to visualise it on the gel. ==> Conclusion : small parts like B0034 can't be cloned as an insert. |
