Design Notes

As a starting plasmid, we used pcDNA5/FRT (Invitrogen), as having this plasmid at hand was an immediate requirement for our project and we did not have the time to construct it from parts. We nevertheless highly modified it by performing two site-directed mutageneses to remove prohibited cutsites, we removed the CMV promoter it contained and inserted JeT, a well-described[1] synthetic promoter which we modified to contain a HindIII cutsite between the proximal and the core promoter for promoter screening. We also added full BBB_2 (Tom Knight) sites to it. Then, we synthesized it by Assembly PCR and inserted it via a MfeI and a PstI site. We then fixed eGFP plus a Kozak-sequence (eukaryotic RBS) into the plasmid backbone by cutting with PstI and BClI

Note: The promoter that is measured can be sequenced by using CCCCTATGGTGCACTCTCAG as a primer.
