DBCO-Lys(m-PEG4)-Val-Cit-PAB(m-PEG4)-MMAE featured 393 SMILES OCC1CCN(CC1)C1=CC=C2C(=O)N(C3CCC(=O)NC3=O)C(=O)C2=C1 Purity (HPLC)SOLU 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 PEG4 is attached to the commonly used self immolative para aminobenzyl (PAB) moiety to further
