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

Sensor construction hbpR/PhbpC
The amplification by PCR was performed another time to amplify BBa_B0015 with overhangs. Protocol was the same as 08/19/2014.
To verify PCR products, 10 µl was loaded on a 1% agarose gel with 2 µl of loading dye 6X.
A really slight band was visible between 200 and 300 bp. It was to weak to obtain a picture with the camera. According to the ladder scale, the band correspond to 20-30 ng, so approximately 2-3 ng/µl of DNA for the PCR product.

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:
