Conjugates containing a targeting ligand, such as an antibody, a therapeutically active drug and a branched peptide linker. The branched peptide linker contains two or more amino acid moieties that provide an enzyme cleavage site. The number of drugs capable of being bonded to the branched linkers varies by a factor of two for each generation of branching.
