ABSTRACT:
Novel clearing agents comprising hexose derivatized human serum albumin and ligand molecule(s) are provided. These clearing agents are useful in pretargeting methods to clear previously administered anti-ligand containing conjugates. Preferably, the hexose is mannose or galactose and the ligand and anti-ligand are respectively biotin and avidin or streptavidin.
