Lab Work
Wet Lab
- We tested C0040 + B0015, P1010 + B0015, C0060 + B0015 and J23100 + B0032 to see if the ligation succeed. The results were disappointing. None of them were properly ligated.
- We made some MiniPreps of some other ligated parts (E0022 + B0015, J23109 + J23032, I712074 + J23082, GFP-LVA + B0015, GFP-LVA + pSB1A2 and C0062 + B0015). After that, we did a PCR using the VR/VF2 primers to see whether these ligations worked or not. E0022 + B0015, GFP-LVA + pSB1A2 and C0062 + B0015 were OK. J23109 + J23032, I712074 + J23082 and GFP-LVA + B0015 gave mixed results. Some of the colonies contained ligated parts, others did not. So we have to try to isolate the right colonies.
- We also started to construct the T7 polymerase with UmuD tag, using PCR.
- We electroporated some ligated parts: R0084 + B0032, R0062 + B0032, R0084 + J23022 and C0012 + B0015
- We made a liquid culture of parts B0032, C0060, C0062, P1010, ?. On Monday, we can MiniPrep them.
- We also made a liquid culture of Top10 cells to make new electrocompetent cells.
Dry Lab
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 thouh 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.
