Copy number of Receiver Plasmid
Design
レシーバーのコピーナンバーを変えることで、応答までの時間を変える
コピーナンバーを変えれば、レシーバーによるLuxRの合成量は変化する
AHLを受け取るLuxRが変わるので応答閾値までの時間が変わると考えた
Experiment
- High Copy Receiver[http://partsregistry.org/Part:BBa_T9002 BBa_T9002 (AHL Reporter)]
- Medium Copy Receiver
Result & Discussion
more about Plasmid Copy number
- クオラムセンシングに関わる遺伝子のベクタープラスミドのコピーナンバーを少なくすることで、遺伝子発現が遅くなる
- それと同時に、遺伝子発現の最大値自体も少なくなってしまう
more about experimental result
Method
- 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).
- Inoculated them independently in liquid media. Incubated at 37°C 12h.
- Inoculated again in Fresh liquid media upto about OD600=2 at 37°C
- Washed sender and receivers.
- Mixed them. (Sender:Receiver=1000μL:1000μL)
- Incubated at 30°C.
- Measured intensity of green fluorescence at regular time intervals.(Fluoroskan AscentR FL&Fluoroskan AscentR Thermo ELECTRON CORPORATION)
