Mal-Acetyl-Dap(m-PEG4)-Gly-Gly-Phe-Gly-PAB(m-PEG8)-PNP dbco-lys-m-PEG4 allowing the non-internalized probe toSOLU 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. Additionally, m PEG8 is attached to the commonly used self immolative para aminobenzyl (PAB) moiety to further increase aqueous solubility. The PNP
