YFP:tetR

Part:BBa_K606025:Experience

Designed by: Kvin Yauy   Group: iGEM11_Paris_Bettencourt   (2011-07-27)

Characterization: Biobricked YFP:TetR

Parts construction:
Origins of YFP:TetR are from pFX234 of D. Lane (Toulouse 2 University).

Cloning plan of YFP:TetR construction



We characterize it with TetO Array from pDAG479 plasmid of F-X Barre and D. Lane (Kinetics of plasmid segregation, Molecular Microbiology, 2004).

Microscopy of double transformed pDAG470 / Biobricked YFP:TetR in E. Coli:

To characterize this part properly, we took pictures of different strains containing YFP:TetR alone and both TetO array (from pDAG479, D.Lane) and expression YFP:TetR system (BBa_K606027).

The TetR-YFP construct which (emitter part) occasionally shows gross aggregated YFP.
After observing the cells carrying both the TetO and YFP:TetR constructs, we can obviously distinguish glowing dots in some cells. They reflect the behavior we expected.
