Method

To characterize quorum sensing crosstalk, constitutive AHL senders were mixed with constitutive receivers and measure fluorescence intensity.

  1. Transformed Senders into E.coli strains(JW1908/XL10GOLD) and Receiver into E.coli strain(JW1908).
  2. Inoculated them independently in liquid media. Incubated at 37°C 12h
  3. Mixed them.
  4. Incubated at 30°C.
  5. Measured intensity of green fluorescence at regular time intervals.

Result

1.Crosstalk test at 30°C

Fig. senders crosstalk test. senders strain XL10Gold,Receiver strain JW1908.Reaction temparature was 30°C.
