Exemplary HPLC chromatograms as recovered from the radioactivity channel (top panel) detecting (#1) free 68Ga and (#2) 68Ga-DKFZ-PSMA-11. Bottom panel showing DKFZ-PSMA-11 UV-signal detected simultaneously (λ: 214 nm). Samples were analyzed: (A) immediately after adding 68Ga-activity; and (B) after 20 min incubation duration.
