a Calibration curve of metoclopramide in the range of 0.1–5 μg/mL measured at a wavelength of 225 nm. The limit of detection and limit of quantification were 0.2 μg/mL and 0.7 μg/mL, respectively. b Gradient for the analytical RP-HPLC for the quality control of [11C]metoclopramide. The mobile phase consist of solvent A: aqueous acetonitrile (90%), solvent B: water and solvent C: aqueous ammonium phosphate buffer (50 mM), pH 9.3 adjusted with NaOH
