Binfunctional carboxylic acid-carboxylic acid linker

Mal-Acetyl-Dap(m-PEG4)-Val-Ala-PAB(m-PEG4)-MMAE tag The water soluble 5(6)-FAM PEG3SOLU KNEX cleavable linker features a Val Ala dipeptide. 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 PEG4 is attached to the commonly used self immolative para aminobenzyl (PAB) moiety to further increase aqueous solubility. The payload is monomethyl
