pRE-RBS-Cro-RBS-CII-TT-ptrp-RBS-CI-TT-pR-RBS-CIII-RBS-RFP-LAAssrAtag-TT-pRM-RBS-GFP-LVAssrAtag


This is the whole characterization circuit of Signal Filter prokaryote version([File:http://2016.igem.org/Team:HUST-China Details see to HUST-China 2016 wiki]) as Fig1 shows.

Here is how we conduct our characterization: We employ T7 and ptrp as our input sensors and BL21 as host strain. When induced by IPTG,Cro and CII are expressed under T7 promoter and CII will give a positive feedback to enhance Cro's expression by promoting pRE. Accumulated Cro will stably bind to the bingding site within pRM thus repress GFP and at the same time RFP expression will not be interrupted (see to Fig2)

When IAA is added, CI will be expressed to further block pR. And with CII's degradation by Ftsh, GFP expression will gradually comes up to a stable state. Meanwhile, RFP level will decrease by protease degradation system through LVAssrA tag. (see to Fig3)
