Interaction among EGCG, LL-37, and LTA of S. mutans. Graphs show the change in delta frequency after injecting LTA and/or LL-37 on the sensor of quartz crystal microbalance. Five microliters of LTA (1 mg/mL) and/or LL-37 (8 mg/mL) were injected. The final concentrations of LTA and LL-37 were 10 and 80 μg/mL, respectively. LTA without initially binding EGCG was injected on the sensor as a control. Data presented are representative of three independent experiments with similar results
