Kit and method for targeting

摘要

The invention describes a novel kit or method for the delivery of pharmaceutical or diagnostic compounds to target cells in the body. This kit comprises a monospecific antibody with multiple binding sites, which antibody recognizes a target associated antigen, and a ligand-effector moiety, of which the ligand has been derived from the target associated antigen or analogue thereof. Specifically the invention relates to targeting cytotoxic drugs or radioisotopes to tumor cells. The preferred antibody is a human IgM and the ligand is preferably the epitope cognate to said antibody.
