DBCO-Lys(m-PEG4)-Val-Cit-PAB(m-PEG8)-Exatecan Cy5 Product Name Thalidomide-O-acetamido-PEG7-OH Synonyms Thalidomide-4'-O-acetamido-PEG7-OHSOLU KNEX cleavable linker features a Val Cit dipeptide. 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 further
