Figure 5. Inhibition curves of the binding of [¹⁸F]FBuEA-GS 3 to L-PGDS (human) at the presence of the inhibitor FBuEA-GS 3 in various concentrations. Data was obtained from single measurement.

(a) The plot of 5 sec. equilibrium. The maximal binding ratio of the control group was 16% and the non-specific binding (nsb) ratio was 6%. (b) The plot of 10 min. equilibrium. The maximal binding ratio was 13% and the non-specific binding (nsb) ratio was 5%.
