オートインデューサー不活性化酵素であるAiiAをレシーバー菌で発現させることにより、レシーバー菌内でのAHL濃度の増加が遅くなるため、AiiAを発現しないレシーバー菌に比べて、GFP発現が遅くなる。

High Copy ReceiverとMedium Copy Receiverのディレイタイムはfollowing procedureによってanalyzeした。

  1. Transformed sender(Ptet-LuxI), high copy receiver(Ptet-LuxR-Plux-GFP-colE1) and Medium copy receiver(Ptet-LuxR-Plux-GFP-p15A) respectively into E coli strains(BD⊿FliC).
  2. Inoculated them independently in liquid media. Incubated at 37℃ 12h.
  3. Inoculated again in Fresh liquid media upto about OD600=2 at 37℃
  4. Washed sender and receivers.
  5. Mixed them. (Sender:Receiver=1000μL:1000μL)
  6. Incubated at 30°C.
  7. Measured intensity of green fluorescence at regular time intervals.(Fluoroskan AscentR FL＆Fluoroskan AscentR　Thermo ELECTRON CORPORATION)
