DBCO-Dap(m-PEG4)-Val-Cit-PAB(m-PEG4)-MMAE Size:25mg 8 SMILES CC1=C(SC=N1)C1=CC=C(CNC(=O)[C@@H]2C[C@@H](O)CN2C(=O)[C@@H](NC(=O)CCOCCOCCOCCC(O)=O)C(C)(C)C)C=C1 Purity (HPLC)SOLU KNEX cleavable linker features a Val Cit dipeptide. In this product, a DBCO Dap(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
