Bacterial-Mammalian promoter with eCFP reporter: BBaK216005 + CArG promoter sequence + BBa_E0420
Our hybrid promoter hopes to add to the systems already in the registry by creating a hybrid promoter that combines the bacterial promoter PyeaR and the mammalian CArG element , both of which respond to exogenous nitrogenous species. Combining the two would allow a more modular NO sensor that can be used in mammalian and bacterial cells interchangeably. The hybrid promoter has been attached to the reporter: enhanced Cyan Fluorescence Protein (eCFP). The hybrid promoter has been characterised by observing expression of flourescent protein, and found to have increased transcription in response to increasing concentrations of potassium nitrate.
The graph above shows the flourescence measured from the expression of eCFP due to the response of the bacterial-mammalian promoter to different concentrations of potassium nitrate. The wavelength reading which corresponds to eCFP is between 440-500nm. The graph clearly demonstrates that between 0mN and 15mM there is a proportional relationship between fluorescence intensity and potassium nitrate concentration. There appears to be a sharp increase in fluorescence intensity between 5mM and 10mM, and the rate at which intensity increase gradually decreases so that there is only a small increase between 15mM and 20mM.
