DIMERIC MOLECULAR COMPLEXES WITH FREE CYSTEINE RESIDUES AND CONJUGATES THEREOF

摘要

The invention relates generally to dimeric molecular complexes comprising two fusion proteins. Each fusion protein comprises a biological effector moiety, a polypeptide spacer sequence, and an IgE CH4 dimerization domain. The dimeric molecular complexes may be conjugated, at a defined site, to other molecules including drug moieties, cytotoxic agents, labels (such as detectable labels), or biocompatible polymers.
