Correlation between GFP generation and cell density
- In order to know how the expression of signal molecules is related to cell density, we use GFP as the intermediate variable between the two variables. First, we determined the function of GFP according to the population of bacteria. Here, we have constructed the part with BioBricks R0040 and E0840. After ligating them together, we measured the amount of GFP expression and corresponding OD values and then worked out the correlation curve using Origin 7.5.
- From the figures above, we can draw the conclusion that the expression of GFP generally takes on a linear function of OD when the OD is between 0.2 to 0.9.
Function Test
After GFP(LVA) cloned successfully,we want to test its function.We ligate it with lac promoter R0010,a strong RBS B0034 and teminator B0015. We transform the plasmid with these parts to E.coli strain TOP10 and induce the GFP express with 0.1mM IPTG.
