deGFP
deGFP is a variant of Green Fluorescent Protein (GFP). It was initially designed by Shin and Noireaux (2010) for expression in cell-free protein synthesis systems and is more efficiently translated than other variants.
Characterisation data for deGFP for collected using the expression construct BBa_K2205002
CFPS Expression of deGFP
CFPS Expression of J23100-deGFP and J23100-sfGFP Constructs: Time course for increase in fluorescence intensity of CFPS systems expressing GFP constructs over time. Each data point is an average of triplicate results, and error bars show +/- standard error. CFPS system with no DNA (Red) was used as the negative control.

Figure 5: Single cell data for E. coli cells expressing deGFP (collected by Exeter iGEM). Columns 1-6: cells expressing deGFP. Columns 7 and 8: wild type Top10 cells. Red parts of the bar are non-fluorescent cells, green parts are fluorescent cells.
Characterization by 2019 BGU_Israel team:
The deGFP can be expressed in a polycistronic plasmid and is expressed and translated in Serratia Marcescens. The deGFP can be used as a reporter gene in mosquito larvae, as they are transparent, and the Serratia are part of their microbiome.
Through integrating engineered Serratia containing a polycistronic plasmid with deGFP, we can track the spread of our engineered bacteria and assume the expression of the other genes from the polycistronic plasmid are occurring as well.
Both figures shows the ability of deGFP to be expressed on a polycistronic plasmid in Serratia Marcescens.
