Comparison of ¹³¹I-PD-L1-Mab tumor uptake and post-blocking uptake in subcutaneous RKO xenograft mice. a After intravenous injection of ¹³¹I-PD-L1-Mab at 48 h, blocking group mice were injected with an excess of unlabeled PD-L1 antibody at the same time as ¹³¹I-PD-L1-Mab was injected. b After intravenous injection of ¹³¹I-PD-L1-Mab at 120 h, blocking group mice were injected with an excess of unlabeled PD-L1 antibody at the same time as ¹³¹I-PD-L1-Mab was injected. The data are expressed as means (%IA/g) ± SD at each time point after injection, *** p < 0.001
