| abstract |
The invention contemplates a composition containing a multispecific ligand containing at least a first ligand binding moiety and a second ligand binding moiety. The first ligand binding moiety specifically binds with a pre-selected first affinity to at least a first ligand. The first ligand has a first biodistribution. The second ligand binding moiety specifically binds with a pre-selected affinity to at least a second ligand. The second ligand has a second biodistribution. The affinity of first and second ligand binding moieties are selected to bias the biodistribution of the multispecific ligand in favour of a selected location of one or both of the ligands. |
