DBCO-Dap(m-PEG4)-Val-Ala-PAB(m-PEG4)-MMAE tetrazine 438 SMILES [N-]=[N+]=NCCOCCOCCNC1=C2CN(C3CCC(=O)NC3=O)C(=O)C2=CC=C1 Purity (HPLC)SOLU KNEX cleavable linker features a Val Ala 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
