Mal-Propionyl-Dap(m-PEG4)-Val-Ala-OH Size:50mg 79 SMILES CC1=C(SC=N1)C1=CC=C(CNC(=O)[C@@H]2C[C@@H](O)CN2C(=O)[C@@H](NC(=O)CCOCCOCCOCCO)C(C)(C)C)C=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. Derived from established ADC linker architectures, SOLU KNEX ADC linkers integrate solubilizing moietiessuch as PEG, amine containing groups, or polysarcosine
