Fig. 1. Time course study and concentration study on 18F-TPP uptake by PC-3 cells.

Fig. 1

PC-3 cells were incubated with normal K concentration (5.4 μM). Time course study demonstrated time-dependent uptake kinetics of 18F-TPP by PC-3 cells. The cellular radioactivity increased gradually and reached the plateau at 60 minutes post incubation (Fig. 1 A: ANOVA, * vs. **: P<0.05; ** P>0.05). Cells incubated with 18F-TPP at different levels of extracellular concentration. The maximum uptake was shown at the concentration of 2 nM (Fig. 1 B: ANOVA, * vs. **: P<0.05; ** P>0.05).
