Parameters for the equations in Formulation <←link> have been experimentally determined in Assay1 <←link>. Analysing the result, the following experiments were turned out to be necessary.
Activation check by cell-produced AHL
Purpose
To check if worker E. coli (Sender) can produce enough AHL for our model to work by using different copy numbers of plasmids.
Result & Conclusion
Not only high copy number plasmid pSB1, also low copy number plasmid pSB4 and pBR produced enough AHL to activate the LacI hybrid promoter in other cells. Especially, pBR remarkably produced AHL in the present experiment.

Activity check on lambda cI-regulated promoter and the lux lac hybrid promoter
Purpose:
To measure and compare the activities of two different promoters + plasmid sets by fluorescence of GFP downstream of each promoter
Samples:
・A4Δｐ pc1-GFP
・A4 hybrid GFP PBR322TetR (+)AHL
・A4 hybrid GFP PBR322TetR (-)AHL
Procedure:
AHL assay Standard protocol
Wash
OD and fluorescence were measured 0, 3, and 6 hours after the fresh culture incubation started.
