Experiments of the YFP concentration design
The planning of the experiments is the following : first we have tested the strains from D. Lane containing YFP:tetR and tetO array. Then we constructed/biobricked the YFP:tetR and tetO array system. To finish with the microscopy step and results of this proof of concept between B. subtilis and B. subtilis / E. coli.
Testing the YFP:tetR strains from D. Lane
In the article [1], strains are growing at 20°C to avoid protein agregation but the problem is that nanotube between B. subtilis has been only proved to exist at 37°C. We test different possibility : at 37°C or 30°C and concentration of arabinose (0% - 0,1% -0,2%) to deal with protein agregation. More pictures and information on the notebook [2].Biobricked system construction
Results and microscopy of the proof of concept
In the emittor cell (B. Subtilis), we have inserted a expressive system for the YFP:tetR. It contains the promoter pVeg, the RBS for B. Subtilis and the YFP:tetR protein. Production of YFP:tetR will diffuse throught the nanotube to the receiver cell.
In the receiver cell (B. Subtilis or E. Coli), there is the tetO array where diffused YFP:tetR will concentrate. The YFP is the monitor of the signal.
The principle of the design is summed up in the image below
