Mal-Propionyl-Dap(m-PEG4)-Gly-Gly-Phe-Gly-PAB(m-PEG8)-PNP pab 612 SMILES: OC(=O)C1=CC=C(C([O-])=O)C(=C1)C1=C2C=C3CCC[N+]4=C3C(CCC4)=C2OC2=C3CCCN4CCCC(C=C12)=C34 Purity (HPLC):SOLU KNEX cleavable linker features a Gly Gly Phe Gly (GGFG) peptide. 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. The
