Prhl(LR)

We newly developed the rhl(LR) promoter (BBa_K1529310) which is activated by C4HSL (Fig. 1).
To characterize the function of this rhl(LR) promoter, we constructed a part Prhl(LR)_GFP (BBa_K1529311) by inserting the rhl(LR) promoter, upstream of a GFP coding sequence.

By using the reporter cells that contain Prhl(LR)_GFP, we measured the fluorescence intensity of the cells induced by C4HSL (Fig. 2). We saw that our new rhl(LR) promoter was actually activated by C4HSL through an induction assay (Fig. 3).
