In vitro uptake and stability of [68Ga]NOTA-folate. a In vitro cell uptake and retention by KB and A549 cells of either [68Ga]NOTA-folate and [99mTc]EC20 (100 nM) alone or a mixture of [68Ga]NOTA-folate and [99mTc]EC20 (100 nM) and folic acid (10 µM) after incubation over 30 min at 37 °C, calculated as a percentage of total added radioactivity. P values were calculated with Student’s t tests, unpaired; *P < 0.05; **P < 0.01; ***P < 0.001; ****P < 0.0001. b Stability studies of [99mTc]EC20 as well as [68Ga]NOTA-folate in human plasma.
