Testing nanotubes with the YFP concentrator system

Design overview

YFP:TetR/TetO array system

More information on the design here.

Summary

Emitter & receiver constructs in B.subtilis (receiver in plasmid)

Emitter construct in E.coli - Receiver construct in B.subtilis (plasmid)

We success to integrate the TetO Array in B. subtilis with the multihost episomal pHM3 plasmid.
Experiments of E. coli (pFX234 plasmid, D. Lane strains) to B. subtilis (TetO Array, pHM3) to follow an eventual fluorescence diffusion by nanotube has been tried.

Movie : Experiment of mixed YFP:tetR (E. coli) & TetO Array (B. subtilis)

We cannot see spot apparitions specific of YFP concentration on TetO Array. This experiment leads us to think that there is no diffusion of the YFP:tetR fusion protein from E. coli to B. subtilis by nanotube.
