RecA(K6)-B0034-eGFP

This is a bioreporter designed with BBa_K629001 RecA(K6) promoter to compare its significance with the optimized K3 (BBa_3020001 promoter and BBa_K4814015 composite reporter), which is derived from team SYSU 2011 aimed to drive the motor system under a radioactive environment. We first treated the bacteria and transferred them into 96-well plates to record the fluorescence and optical density (absorbance at 600nm). However, as we discovered that this method might not be accurate enough, we chose to stabilize them on the microscope slides and took photos of the E.coli. After we processed these images, we calculated the mean value of any completely visible bacteria and used the data points from three independent experiments to plot the following box charts. As can be shown in the following figures, the RecA(K6)-B0034-eGFP design does not illustrate the dosage dependence.

We then use Fluorescence over OD600 (FL over OD) to compare the EGFP signal in different groups. According to BIT 2019 (https://2019.igem.org/Team:BIT/Bio), SFU is used to compare fluorescence. (Specific fluorescence units SFU=RFU/OD600) After we compared the data of three independent experiments, we can observe that in both UV and H2O2, the SFU is directly proportional to the intensity/concentration of the carcinogen. In addition, the performance of K3 is better than K6, showing that the optimized promoter K3 reduced the background noise considerably.
