In this product, a Mal Propionyl Dap(m PEG4) moiety replaces the conventional maleimidocaproyl (MC) unit to enhance aqueous solubility. The Mal Propionyl group may also improve retro Michael addition stability during antibody conjugation. Additionally, m PEG8 is attached to the commonly used self immolative para aminobenzyl (PAB) moiety to further increase aqueous solubility. Derived from
