Sensor construction bphR2/PbphR1
We received sequencing reads: that match perfectly to the registry sequence.

Plasmid with bphR2 gene was purified with NucleoSpin Plamsid protocol (Macherey-Nagel) => we obtained 227,5ng/µL
This plasmid was digested according this protocol:

  1. Add:
    • sterilized water: qsp 20µL
    • template DNA : 500ng
    • buffer 2.1: 2µL
    • BSA: 0,2µL
    • EcoRI: 1µL
    • PstI: 1µL
  2. Reverse for mix
  3. Incubate at 37°C during 45mn
  4. Incubate at 80°C during 20mn
  5. Ligation was not possible because pSB1C3 plasmid was not digested so the digested plasmid (bphR2 gene) was stored at -20°C

Survival test on E.coli BL21:
Bacteria survive again for different concentrations but they were very concentrated

A dilution of the medium has been done for the positive control and the six different concentrations:
