N1-3 Toehold Switch

N1-3 Toehold Switch is one of the synthetic toehold switch that is designed to detect the Neuraminidase 1 (N1) RNA in influenza A virus. iGEM17 Hong Kong-CUHK team designed 3 toehold switches to detect the Neuraminidase 1 (N1) gene (BBa_K2254110, BBa_K2254120, BBa_K2254130).

Switch plasmid is transformed either with its respective trigger or empty plasmid into E. coli BL21 (DE3) cells. Single colony of each set-up was picked to grow overnight culture. Expression of reporter mRFP was done by shaking culture for 6 hours after 1% inoculation when log phase was reached. After harvesting the cells and determining the OD600, cells were washed with PBS buffer, concentrated 10x and then aliquoted in 96-well plates to determine the fluorescent signal by exciting at 584nm and measuring at 607nm. Final fluorescent signal were normalized by OD600 to give the final relative fluorescent unit (R.F.U). Below graph showed the result of N1-1, N1-2 and N1-3 switches (BBa_K2254110, BBa_K2254120, BBa_K2254130).
