Plac + INP-EYFP
Fusion of Ice Nucleation Protein (INP) and Enhanced Yellow Fluorescent Protein (EYFP) under the control of the Lac promoter.
Constructed using the BioSandwich protocol of Edinburgh 2011.
Usage and Biology
Cells expressing this construct are shown on the right. The cells fluoresce yellow under blue light. The INP should carry the EYFP to the outer membrane of E. coli. Our imaging technology was not good enough to confirm this, so we attempted to prove it by other means...
Fractionation experiment
We centrifuged cells expressing BBa_K523013 so that the membrane portion be localised to the bottom of the tube, and compared the fluorescence pattern with a control where EYFP was not fused to INP.

| Control on left. INP-EYFP on right. | The same image passed through GIMP's auto white balance filter. |
These results appear to indicate that the EYFP was successfully transported to the outer membrane; this region is the main source of fluorescence in the INP-EYFP tube.
