Research outputpeer-review


Targeted radionuclide therapy using Terbium-161 (161Tb) is a promising approach for β- and Auger electron therapy. Heat-sensitive biomolecules (e.g. nanobodies) are increasingly being used as carriers in radiometal-based pharmaceuticals, however current radiolabelling techniques require heating (>85 °C) incompatible with heat-sensitive carrier molecules. In this study, we evaluated bifunctional chelators that allow 61Tblabelling under mild conditions using human serum albumin (HSA) and assessed the in vivo stability of the constructs.
