- AvrII/ BamHI: BamHI cutting inside Bxb1
The results show that the cloning failed.
08/09
New cloning of Tp901.1 in pSB1C3, pSB1K3 and pSB1A3.

Minipreps on Tp901.1 are wrong.

New infusion reaction for Tp901.1 with both PCR amplified and linearized plasmids.

18/09
PCR screening failed for unknown reasons. Minipreps done on the previous PhiC31* infusion reaction and gave bad results.

24/09
New infusion reaction with new primers : Vector+Pweak+RBS - Recombinase - Terminator.
26/09
Minipreps on previous infusion reaction gave bad results. We decide to keep on using original sequences of Tp901.1 and PhiC31 integrases for characterizations.
