Panel A: Saturation binding of [125I]-E-IA-BF-PE-PIPZE (0.016 – 1.6 nM) to mouse brain membranes (0.15 mg protein / mL) at 37 °C with a 180 min incubation and haloperidol (1.0 μM) to define non-specific binding. Panel B: Traditional Rosenthal plot for visualization of the relationship between bound radioligand, and the ratio of bound radioligand to free radioligand. Data are from a representative experiment performed in duplicate, and replicated four times to give Kd 0.24 ± 0.01 nM and Bmax 472 ± 13 fmol / mg protein by non-linear regression.
