Reporters
Fluorescent reporters are an important tool in molecular biology, as they are frequently used to label various intracellular processes. In synthetic biology, fluorescent reporters are often used as the output of a genetic circuit, for example to signal the detection of a chemical.
As part of our iGEM project, we implemented a new fluorescent reporter, Dendra 2. In addition, we introduced a new coding sequence for superfolder GFP that is codon optimised for E.coli.
To further characterise these parts, we have conducted a thermostability assay to determine the temperature at which these proteins denature and cease to fluoresce.
Dendra 2
Dendra 2 is a green fluorescent protein that is capable of being irreversibly photoconverted by single-photon stimulation from excitation at 486nm and emission at 505nm wavelength to 558nm excitation and 575nm emission wavelength. Photoconversion can occur using two wavelengths 488 and 405nm (Gurskaya et al., 2006)..

Superfolder GFP
This is a variant of GFP that has been engineered to be faster folding so that it can be used for tagging proteins more efficiently. The variant that we're submitting to the registry has been codon optimised for E.coli.
