Modeling

Aachen REACh approach.png
Our novel biosensor approach
Expression of the TEV protease is induced by HSL. The protease cleaves the GFP-REACh fusion protein to elicit a fluorescence response.

Model of the molecular approach and the output over time
The molecular setup of the novel biosensor (left) yields results indicating a strong and fast fluorescence output after induction (right). A directly inducable system was modeled and added to the plot for comparison. Tinkercell was used for modeling.

The novel biosensor approach was modeled as shown above. The plotted results also include a model of a direct expression of GFP as it appears in traditional biosensors. The strength of the promotor used for the traditional approach is twice as high as the strength of the promotor upstream of the TEV coding sequence in our novel approach. Despite the stronger promotor, a higher GFP concentration is generated in the model of the novel biosensor, proving the stronger and faster output of our construct in theory.
