  • Gel migration
  • Gel extraction of the PCR product of K808030 and pDG011.

The bacteria did not grow because the wrong antibiotic was chosen: BBa_J61047 was in pSB1A2 and not pSB1C3.
- Bacterial culture of BBa_J61047 on liquid LB + Amp 1X at 180 rpm, 37°C. The bacteria grew well.
- Midi-prep has been done with the 50mL of BBa_J61047 culture. (dilution 1/1000)
