Lab work

1 - Plasmid DNA Extraction:

by Romain and Sean

Plasmids used:

• BBa_B0015, dble ter
• FNR_RBS_amilCP-Ter DH5αZ1

Protocol

2 - Transformation of competent cells E.coli

by Fabio and Maher

Competent strains used:

• DH5α
• MG1655
• MG1655Z1
• DH5α+ (given by Solenne)

(The strains DH5α, MG1655 and MG1655Z1 were prepared by Mathias and Mathieu)

BioBricks used:

• BBa_J23100 (Amp R)(Dilutions: Concentrated, 0 and 10^-1)
• BBa_J23106 (Amp R)(Dilutions: Concentrated, 0 and 10^-1)
• BBa_J23114 (Amp R)(Dilutions: Concentrated, 0 and 10^-1)

+ pET28a (Kan R)(Dilutions: 0, 10^-1 and 10^-2) (pET28a is a plasmid used to verify that the 4 strains are competent).

Negative control groups:

• pET28a: without plasmid, nothing grows.
• BBa_J23100, BBa_J23106, BBa_J23114: without the BioBrick, nothing grows.

Results:

• pET28a: Nothing grows with the strains DH5α, MG1655, MG1655Z1. But the strain DH5α+ grows well.
• BBa_J23100, BBa_J23106, BBa_J23114: The strain DH5α+ grow well and the 3 others strains grow less. They have to be more concentrated.

Modeling

"by Pierre, Juliette, Arnaud, Eugene"

Discussion around differents modeling possibilities in concertation with Solenne.
