DBCO-Lys(m-PEG4)-Val-Ala-PAB(m-PEG8)-MMAE deuterium-labeled-amine 486 SMILES: NCCCCCNC(=O)C1=CC=C2C(=C1)C(=O)OC21C2=CC=C(O)C=C2OC2=C1C=CC(O)=C2 Purity (HPLC):SOLU KNEX cleavable linker features a Val Ala 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
