Part:BBa_K2598025
lacZ under CGG-regulated promoter pCGG
This part contains lacZ under a CGG-regulated promoter pCGG, T7 RNAP sigma fragment CGG(BBa_K2598011) can direct T7 core fragment to pCGG, inducing the expression of downstream genes. A strong terminator is added to avoid recombination.

Characterization
Figure 1 shows the relationship between the wavelength of light exposed on liquid medium and the intensity of BFP, GFP and RFP E. coli expressed from left figure to right figure respectively. We got the data through flow cytometer and analyzed it to get the figure. The y-axis is the number of cells, and the x-axis is fluorescence intensity. And every color is E. coli that grows for 8 hours under the light of the corresponding wavelength. We can see E. coli has the highest blue fluorescence expression under blue light from the left graph. And We can also see E. coli has the highest green and red fluorescence expression under green light and right light from the middle and right graph respectively. So this figure proves that our system and our parts can work well.
Characterization
Figure 2 shows the relationship between fluorescence intensity and excitation wavelength. The x-axis is wavelength of 10h illumination. The solid medium gradually emerged and the y-axis is RGB figure of fluorescence in illuminated solid medium. This curve illustrates how our system responses to different excitation wavelength, which perfectly meets our expectation. So this figure proves that our system and our parts can work well.
