The RNA sequence was obtained from the Georgia Institue of Technology that was number 2 of the 144 generation orthogonal toehold switch collection from the Collins Paper titled, Toehold Switches: De-Novo-Designed Regulators of Gene Expression.
Design Notes
This part is meant to be used as a proof of concept for the K2550000 Toehold switch. It needs to be ligated into a high copy number plasmid that has a different antibiotic resistance than the Toehold switch plasmid in order to allow the E. coli cell to recognize two distinct plasmids to copy each plasmids at proportional amounts. Lambert iGEM used pSB6A1 for the trigger in our own trials. Dual transformation with both plasmids will result in blue coloration from the LacZ gene.

DNA sequences to build the trigger part was obtained from the Styczynski Lab at Georgia Institute of Technology
