Fig. 2. Temporal signal stabilities of firefly and renilla luciferase reporters in planktonic and biofilm cultures of S. mutans, S. gordonii, and S. sanguinis.

Fig. 2

Presented here are the average luminescence values (RLU) and standard deviations normalized to the cell density over a 15 min. time course after luciferase substrate addition (n=3). A) planktonic firefly luciferase activity; B) planktonic renilla luciferase activity; C) biofilm firefly luciferase activity; D) biofilm renilla luciferase activity.
