Biodistribution of68Ga-Ex4NOD12,68Ga-Ex4NOD27 and68Ga-Ex4NOD40 in CD1 nu/nu mice with subcutaneous CHL-GLP-1R-positive tumours. Values are mean percentages injected dose per gram tissue (n = 4. Error bars SD). Blocking was performed by pre-injection of 100 μg excess of the corresponding unlabelled compound. Mice were sacrificed 0.5, 1 and 2 h after injection. The significance between the 2 h unblocked and blocked was tested by Student's unpaired t test (*p < 0.05; **p < 0.01).
