Part:BBa_K2557029
TetO-EF1α promoter -EGFP
The EF1α promoter and EGFP coding sequences were ligated in sequence to characterize promoter strength.
Sequence and Features
Usage and Biology
This composite part can transduce the input signal of the upstream TEV protease into the fluorescent signal of Enhanced GFP. Here, we characterized the combination of the TetO-EF1α promoter.
Characterization
Fig.1 Inhibition of tetR on promoter with tetO sequence (A)Fluorescence microscope observation of HEK 293T only transfect with plasmids containing promoters with tetO sequence. (B)Fluorescence microscope observation of HEK 293T transfect with plasmids containing promoters with tetO sequence and tetR.
Fig. 1A shows that the strength of the three promoters in HEK 293T cells is from strong to weak: Ubc > EF1 α > miniCMV. Fig. 1B shows that TetR has obvious inhibitory effects on the three promoters downstream of TetO.
