BBa_K4174001
To test the effectiveness of our improved parts, our team grew the original construct (BBa_J45995), our improved mRFP1 construct (BBa_K4174001), and our improved sfGFP construct (BBa_K4174002) in E. coli NEB5α in a plate reader. They were grown at 37°C using continuous shaking. For red fluorescence measurements, we used an excitation value of 584 nm and an emission value of 610 nm. The values for red fluorescence are reported below.
Based on the graph above, the bacterial cells engineered with our mRFP1 construct appear to have entered stationary phase around 16 hours. As seen in the graph, our mRFP1 construct produces more red fluorescence than the original circuit. The other measurements taken are for our sfGFP construct and untransformed E. coli NEB5α cells, both of which serve as negative controls for red fluorescence.
As seen in the image above, qualitative results reveal that our mRFP1 construct produces more red fluorescence than the original construct. Here, our mRFP1 construct is on the far left, and is visibly more red that the original GFP construct.
BBa_K4174002 To test the effectiveness of our improved parts, our team grew the original MIT 2006 construct, our improved sfGFP construct (BBa_K4174002), and our improved mRFP1 construct (BBa_K4174001) in E. coli NEB5α in a plate reader. They were grown at 37°C using continuous shaking. For green fluorescence, we used an excitation value of 485 and an emission value of 528. The values for green fluorescence are reported below.
As seen in the graph above, both the sfGFP and MIT GFP constructs enter stationary phase right before 14 hours, but our improved sfGFP circuit is much more fluorescent. The other constructs are our RFP construct and untransformed E. coli cells, both of which serve as negative controls for green fluorescence.
As seen in the image above, qualitative results reveal that our improved constructs are more fluorescent than the original construct. Here, sfGFP is on the far right, and is visibly more brightly green that the original GFP construct.
