Figure 1: Instant thin-layer chromatography of 68Ga-DOTA-Ubiquicidin 29–41 (a) and free Ga-68 (b) Using Sodium citrate (0.1M, pH 5.5) as the solvent. Free 68Ga moved with the solvent front to the top (Rf = 1.0), while labeled product stayed at the origin (Rf = 0–0.4). (c) Gradient high-performance liquid chromatogram with 0.1% TFA/H2O and acetonitrile as solvents showed the retention time of 7.2 min for68Ga-DOTA-Ubiquicidin 29–41
