T7 RNAP + IPTG->PoPs (Mutant II)
This is a mutant T7 promoter that includes a lacO sequence. This is repressible by the LacI protein and is induced in the presence of IPTG. The promoter sits in the 5' region of the gene of interest and initiates transcription when the cell expresses T7 RNA polymerase. Be sure you are using a cell strain that is compatible with T7 expression vectors.
The following parameters were calculated and compared against the "wild-type"</html> [1] The following parameters were calculated:
| Promoter | BBa K921000 | BBa K921001 | BBa K921002 |
|---|---|---|---|
| Transcription Strength | 97% | 72% | 127% |
| Translational Efficiency | 6% | 6% | 94% |
Fluorogen activating proteins were used as protein reporters in our characterization experiment as described here. Here, a saturating amount of malachite green was added to each well of a 96 well plate and fluorescence values were recorded over time. Our model was used to describe the behavior of our time lapse data using differential equations and fitting algorithms.
The Spinach aptamer was used as an RNA reporter in our characterization experiment as described here. Here, a saturating amount of DFHBI was added to each well of a 96 well plate and fluorescence values were recorded over time. Our model was used to describe the behavior of our time lapse data using differential equations and fitting algorithms.
Note: Not included here are the properties of our characterization method. To learn more about how we characterized this set of promoters, click here.
