More details on fully functional new biobricks

• From plasmids pFA6a-link-yoSuperfolderGFP-Kan (44901) and pFA6a-link-yoSuperfolderGFP-Ura (44873) we ordered to Addgene, we created and submitted the two parts of the split yeast optimized superfolder GFP (N-terminal part (BBa_K1486029) and C-terminal part (BBa_K1486035)). We attached them to the ADH1 terminator, regulating the transcripion of our fusion proteins and to the selection markers Kan and Ura3. We stressed our cells under various conditions to trigger the HOG pathway and were able to show that interaction of Hog1 and Pbs2 in response to osmotic stress allowed the re-assembly of the full GFP protein.

Further Characterization and Improvement of Parts Already in the Registry

• We realized that Calgary's CpxR reporter biobrick was missing the regulatory part of the sequence, so we repaired it and sent it as our BBa_K1486048. The BioBrick was further developed by testing the native CpxR target sequence that is found in front of CpxA in the E.coli genome (as Calgary's part did not include the whole sequence). These are BioBricks BBa_K1486049 and BBa_K1486050, with the promoter in forward and reverse direction respectively.
• Submitted the two parts of the split of EPIC Firefly luciferase (N-terminal part (BBa_K1486016) and C-terminal part (BBa_K1486017)) from Cambridge 2010. The plasmid (BBa_K1486018) containing the two parts of the split separated by a spacer can be very useful as a negative control or to establish a background noise for a complementation assay experiment.
• Compared the EPIC Firefly luciferase from Cambridge 2010 team to the renilla luciferase (BBa_K1486022) in the same conditions, to determine which one is best suited for a complementation assay experiment. The full and split luciferases has been compared. Renilla luciferase (full and splits(BBa_K1486021)) have been submitted.

Microfluidics

• Design of SmashColi - a testing chip to analyse the effects of different mechanical stresses on cells
• Design of FilterColi - a testing chip to analyse the effects of different osmotic stresses on cells
• Design of the BioPad - a large-scaled chip implemented to be the touch-senstive interface of our final trackpad
• Design of CleanColi - an "on-chip waste treatment" unit that can be integrated at the end of any chip to decontaminate GMOs or pathogens

Human Practices

• Met with a journalist from the biggest newspaper of our region (Le Temps) and got an article about our project.
• Our work was commented by Bent Stumpe, inventor of the touchscreen, as well as Rolf Heuer, the current director of the CERN, in Geneva.
• Organized an outreach event with 80 highschool students at EPFL, teaching them about synthetic biology as well as laboratory techniques and made them participate in a game called « mini iGEM ».
• Presented iGEM and our work at the Hackuarium, the new BioHackerspace in Lausanne.
