Post-labeling stability analysis. a Release fraction of the radioactivity from 18F-FDG-labeled RBCs during a 180-min incubation in plasma at 37 or at 0 °C (n = 4). b Thin-layer chromatography of extra- (left, release) and intracellular fluid (right, hemolysis) after a 60-min incubation of 18F-FDG-labeled RBCs in plasma. Obvious difference between them was seen
