Lab Work

We tested [http://partsregistry.org/Part:BBa_C0040 C0040]+[http://partsregistry.org/Part:BBa_B0015 B0015], [http://partsregistry.org/Part:BBa_P1010 P1010]+[http://partsregistry.org/Part:BBa_B0015 B0015], [http://partsregistry.org/Part:BBa_E0022 E0022]+[http://partsregistry.org/Part:BBa_C0060 C0060] and [http://partsregistry.org/Part:BBa_J23100 J23100]+[http://partsregistry.org/Part:BBa_B0032 B0032] to see if the ligation succeeded. The results were disappointing. None of them were properly ligated. (see Gel 1).

General
Hybrid promoter in front of ccdB is not enough because the timer will have started. So the safest way might be to use antisense LuxI (leaky though it is) and the hybrid promoter. If it's too much work/costs, just antisense LuxI maybe.
The following parts will have to be on a higher copy number plasmid (preferably a pSB5X#): antisense LuxI, the ribokey and the 434 without the LVA tag.
Modeling
Worked some more on the sensitivity analyses with a bunch of new strange results... Probably have to think of a better way to represent sensitivity, the formula of ETH Zürich 2007 may not apply that good to our situation. Apart from this, we're still waiting for the first lab-results to come in so we can verify how representative the parameters in the simulation are.
