Mal-Propionyl-Dap(m-PEG4)-Val-Cit-PAB(m-PEG8) Size:100mg CC1=C(SC=N1)C1=CC=C(CNC(=O)[C@@H]2C[C@@H](O)CN2C(=O)[C@@H](NC(=O)CCCN2CCNCC2)C(C)(C)C)C=C1 Purity (HPLC) >= 95%SOLU KNEX cleavable linker features a Val Cit 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 PEG8 is attached to the commonly used self immolative para aminobenzyl (PAB) moiety to further increase aqueous solubility. Derived from
