Mal-Propionyl-Dap(m-PEG4)-Gly-Gly-Phe-Gly-PAB(m-PEG8) Size:100mg 405 SMILES [N-]=[N+]=NCCOCCOCCOC1=CC=C2C(=O)N(C3CCC(=O)NC3=O)C(=O)C2=C1 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.
