Abstract
Antibodies bearing engineered cysteine residues (termed THIOMAB™ antibodies) enable the site-selective attachment of a drug, label or other payload for specific delivery to certain tissues (e.g., tumors). This Chapter describes detailed methods we have developed and optimized for the conjugation, purification and analysis of THIOMAB™ antibody drug conjugates (TDCs).
