SuperNova activity


We wanted to test the activity of [http://parts.igem.org/Part:BBa_K1491018 Supernova] on the colonies, so we made a protocol where we illuminated petri dish with a 16,5 Candela 595nm Diode (lumex ssl-lx5093syc/g) for 2 hours.

With the following protocol :

  • Transform 100µL TG1 with Eprc - SN (psb1C3 plasmid, 5µL)
  • To get an adequate number of colonies :
  • Into 2mL LB add 2µL of 2 DO TG1
  • Pipet up and down
  • From the first dilution, take 8µL and dilute it into 1mL LB
  • Spin at 5000rpm for 10min
  • Remove 850µL supernatant
  • Resuspend pellet (even if you can't see it)
  • Spread remaining 150µL on petri dish
  • Immediatly put on 590nm light / put control in dark
  • After two hours, incubate overnight
  • Count colonies
Exposed Not exposed
Supernova 1496 3672
RFP 3545 3638

The with a RFP plasmid as a control we show there's no decrease.

With this experiment, we can conclude that supernova allows us to divide the number of colonies by 2,45.
