The dark blue points in the graph top left show the activation of gene expression when pLux is induced by 3OC6-HSL (Lux-AHL) binding to the corresponding LuxR regulator. The observed transition occurs at a concentration of approximately 1 nM 3OC6-HSL. The light-blue curve plotted shows modeling data of pLux induced by 3OC6-HSL (Lux-AHL) binding to the corresponding LuxR regulator. This curve from the model and the dark blue data point gained in experiments were plotted as a reference in all the other graphs describing pLux. | The dark blue points in the graph top left show the activation of gene expression when pLux is induced by 3OC6-HSL (Lux-AHL) binding to the corresponding LuxR regulator.

Crosstalk can be observed for the cases where the 3OC12-HSL (Las-AHL) binds the LuxR regulator. Additionally for 3OC12-HSL binding to its corresponding regulator LasR and then binding to the pLux as seen in the middle of the top row and center of the matrix. | Crosstalk can be observed for the cases where the 3OC12-HSL (Las-AHL) binds the LuxR regulator.

For the case of Las-AHL binding the LasR and subsequently the promoter pLux, the transition occurs at 1 nM and reaches 0.5 fold the fluorescence as pLux induced by 3OC6-HSL binding LuxR. | For the case of Las-AHL binding the LasR and subsequently the promoter pLux, the transition occurs at 1 nM and reaches 0.5 fold the fluorescence as pLux induced by 3OC6-HSL binding LuxR. | ||
In the case of 3OC12-HSL binding LuxR and inducing the promoter pLux, the transition is observed at approximately 100 nM and severe crosstalk is observed. | In the case of 3OC12-HSL binding LuxR and inducing the promoter pLux, the transition is observed at approximately 100 nM and severe crosstalk is observed. | ||

Observation of C4-HSL has shown, that there is no significant crosstalk with the LuxR and LasR regulators binding C4-HSL and subsequently to pLux. This is indicated on top right and middle right graphs. | Observation of C4-HSL has shown, that there is no significant crosstalk with the LuxR and LasR regulators binding C4-HSL and subsequently to pLux.
