P70c-UTR3-deGFP
Under the combination of P70c promoter and UTR3, green fluorescent protein can be expressed.
Usage and Biology
According to the lecture, we selected three promoters for Cell-Free systems: P70a, P70b and P70c and combined with three Ribosome Binding Sites (RBS) UTR1, UTR2 and UTR3 to express deGFP gene. The fluorescence intensity of deGFP was measured by adding varied concentrations of plasmids into the Cell-Free system. Simultaneously, experimental results and modeling data were compared, and the optimal promoter RBS combination was obtained in order to express deGFP in a Cell-Free system.
Kinetics of deGFP expression
