Mal-Acetyl-Dap(m-PEG4)-Val-Ala-PAB(m-PEG4) Size:50mg 334 SMILES O=C1N(C2CCC(=O)NC2=O)C(=O)C2=C(OCCOCC#C)C=CC=C12 Purity (HPLC)SOLU KNEX cleavable linker features a Val Ala dipeptide. In this product, a Mal Acetyl Dap(m PEG4) moiety replaces the conventional maleimidocaproyl (MC) unit to enhance aqueous solubility. The Mal Acetyl 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. Derived from established
