In this product, a DBCO Lys(m PEG4) moiety replaces the conventional maleimidocaproyl (MC) unit to enhance aqueous solubility. DBCO is a strained alkyne commonly used in copper free click chemistry, specifically in the strain promoted azide alkyne cycloaddition (SPAAC) reaction. Additionally, m PEG8 is attached to the commonly used self immolative para aminobenzyl (PAB) moiety to
