Fig. 1From: Non-specific irreversible 89Zr-mAb uptake in tumours: evidence from biopsy-proven target-negative tumours using 89Zr-immuno-PETDistribution of 89Zr-mAbs in healthy tissue: A convection of mAbs across the vascular endothelium into the interstitial space and return to circulation via lymphatic system; B mAb uptake into endothelial cells via pinocytosis and FcRn-mediated return to vascular or interstitial space; C catabolism of FcRn-unbound mAbs; D binding to target receptors.
