Biodistribution analysis at different pre-targeting time points (10 h, 20 h, and 30 h). a Tissues uptakes of HCT116 tumor-bearing mice at 2 h p.i. of 68 Ga-L-NETA-DBCO with different pretargeting time. b Tumor uptakes of different pretargeting time points. c–e Tumor/Muscle ratios, Tumor/Liver ratios and Tumor/Spleen ratios of different pretargeting time points. All bars represent as means ± SD (n = 4). *P < 0.05; **P < 0.01; ***P < 0.001
