Fig. 2From: Development of new copper-64 labeled rhodamine: a potential PET myocardial perfusion imaging agentTLC chromatograms of (A) 64Cu-NOTA- and (B) 64Cu-NOTAM rhodamine conjugates. In the TLC chromatograms, the free copper remained at the origin (Rf: 0–0.15) while the radiolabeled.64Cu-complexes moved to Rf values of 0.8–0.95Back to article page
