rm/lac hybrid promoter

We newly developed the RM/lac hybrid promoter (BBa_K1139151) which is activated by CI and repressed by LacI (Fig. 1).
To characterize the function of this RM/lac hybrid promoter, we constructed a part PRM/lac-GFP (BBa_K1139150) by inserting the RM/lac promoter upstream of a GFP coding sequence.

Fig. 1. Our newly designed hybrid promoter

By using the reporter cells that contain PRM/lac-GFP, we measured the fluorescence intensity of the cells induced by CI and IPTG (Fig. 2). We saw that our new RM/lac hybrid promoter was actually activated by CI through an induction assay (Fig. 3).
