Part:BBa_K1119008

Designed by: Hyun Jung Lee   Group: iGEM13_Hong_Kong_HKUST   (2013-09-16)

CMV promoter - GFP - hGH polyA tail

This is a mammalian GFP generator used for characterization of our CMV promoter (BBa_K1119006). This GFP generator contains the CMV promoter sequence with GFP reporter in RFC25 format(BBa_K648013) and hGH polyA terminator (BBa_K404108).

This GFP generator was then transfected into HEK293FT cells and in vivo green fluorescence signal was observed under confocal microscope.

pEGFP-N1 (Clontech) served as the positive control. It contains the CMV promoter and EGFP reporter. A GFP generator that does not contain the CMV promoter was used as the negative control.

The detailed protocol of our characterization can be found in HKUST iGEM 2013 Wiki.

Figure 1. CMV promoter drives expression of GFP. HEK cells transfected with pCMV-GFP gave GFP signals. HEK cells transfected with the commercial pEGFP-N1 showed similar results, while the same construct without any promoter did not give any GFP signals.

Improved Part

iGEM Technion 2017 improved this part to BBa_K2520006. This improved device contains a TRE promoter instead of the original CMV, to allow for inducible expression of GFP within mammalian cells.
