Mal-Acetyl-Dap(m-PEG4)-Gly-Gly-Phe-Gly-PAB Size:50mg 2 SMILES [2H]C([2H])([2H])OC1=CC(N)=C(C)C=C1 Purity (HPLC)SOLU KNEX cleavable linker features a Gly Gly Phe Gly (GGFG) peptide. 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. Derived from established ADC linker architectures, SOLU KNEX ADC linkers integrate solubilizing moietiessuch as PEG, amine containing groups, or
