Design Notes

We ordered the synthesized sequence. Originally ordered sequence: forward (5’ AATGcccacatactctgatgatccttcgggatcattcatggcaa 3’) and (5’ AAGCttgccatgaatgatcccgaaggatcatcagagtatgtggg 3’) with AATG and AAGC respectively being a linker, to facilitate further manipulations (swapping of the part or attaching to different promoters).

The forward and reverse sequences were phosphorylated, annealed and ligated to other parts using T4 DNA ligase.

The Downstream F30 scaffold should be used with the Upstream F30 scaffold (BBa_K3380101), both flanking a fluorescent RNA aptamer.

The F30 scaffold was engineered by Filonov et al. in 2015. It is based on the Φ29 RNA three-way junction motif studied by Shu et al. in 2014.
