Mal-Propionyl-Dap(m-PEG4)-Val-Ala-PAB(m-PEG4)-MMAE Size:5mg 338 SMILES OCCOCCOC1=C2C(=O)N(C3CCC(=O)NC3=O)C(=O)C2=CC=C1 Purity (HPLC)SOLU KNEX cleavable linker features a Val Ala dipeptide. In this product, a Mal Propionyl Dap(m PEG4) moiety replaces the conventional maleimidocaproyl (MC) unit to enhance aqueous solubility. The Mal Propionyl group may also improve retro Michael addition stability during antibody conjugation. Additionally, m PEG4 is attached to the commonly used self immolative para aminobenzyl (PAB) moiety to further increase aqueous solubility. The payload is
