Mal-Propionyl-Dap(m-PEG4)-Val-Ala-PAB(m-PEG8)-Exatecan Size:25mg Product Name Lenalidomide-PEG3-OH Synonyms Lenalidomide-4'-PEG3-OHSOLU 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. Additionally, m PEG8 is attached to the commonly used self immolative para aminobenzyl (PAB) moiety to further increase aqueous solubility. The payload is
