Method

  1. Transformed Senders into E.coli strains(JW1908) 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 37°C.
  5. Measured intensity of green fluorescence at regular time intervals.

Left:

  1. 蛍光強度が、30°C,37&degC;に比べて極端に低く,Sendersの培養液を添加しなかった反応液と差がほとんどなかった.LuxI,LasI,RhlI,LuxR,GFPすべての発現量が減っていたためと考えた.
  2. LuxI,RhlIの培養液を,混ぜた反応液に比べて,LasIの培養液を混ぜた反応液は,最大蛍光強度が小さかった(約1/2).

Right:

  1. RhlIにLVAtagのついているものは,LVAtagのついていないものに比べて最大蛍光強度が小さかった.
