Cell binding and internalization of [68
Ga]6 and [68
Ga]7 (A). Specific cellular uptake was evaluated by blockage using 100 μM 2-PMPA. (B) The graph shows the release of radioactivity from cells in percentage of initially bound compound. (C) The release of radioactivity related to the initial cellular uptake derived from A. Values in A and C are expressed as percentage of applied radioactivity bound to 106 cells. Data are expressed as mean ± SD (n = 3).
