Fig. 3From: Radiobiological and dosimetric assessment of DNA-intercalated 99mTc-complexes bearing acridine orange derivativesActivity-dependent cellular uptake of 99mTc-C3 (a) and 99mTc-C5 (b) in PC3 cells, after 24 h incubation at 37 °C. Cells were incubated with 7.4 kBq–7.4 MBq of HPLC purified radiocomplexes. Internalization, surface-bound, and cellular uptake were expressed as the activity (cpm) measured in each fractionBack to article page
