Plasmid vectors were purified from E. coli via miniprep (Qiagen)and the concentration for each mini-prepped test device was determined using a Qubit fluorometer and diluted to 0.5 ng/µl. The diluted pSB1C3 vectors were linearised using a 2 step PCR system following a Q5 Polymerase protocol (NEB). This protocol utilised forward and reverse primers with Tm values of 72°C. The internal standard and mNeonGreen primers were designed by using the NEB Tm calculator and Benchling. The Internal Standard bind in a non-coding region of the pSB1C3 vector – a region between the chloramphenicol resistance gene and the ORI. The mNeonGreen primers consisted of 6 reverse primers, one complimentary to each test device promoter, and a single forward primer over the terminator. The amplified DNA was then digested with DpnI, heat treated to inactivate the enzyme and assembled via Gibson Assembly using the NEBuilder HiFi DNA Assembly Kit. Following their protocol, a 2-fragment reaction with 0.5 pmol of DNA in a 2:1 insert to vector ratio was done and transformants were plated onto agar plates with the appropriate antibiotic (LB+cam for each test device and LB+amp for the controls). Following growth of colonies, plasmid DNA was miniprepped from DH5-α transformed with both the internal standard and the mNeonGreen vector and sequenced to verify presence of the genes.
