DBCO-Dap(m-PEG4)-Val-Ala-PAB-PNP Pomalidomide Product Name Lenalidomide-acetamido-O-PEG2-C2-Cl Synonyms Lenalidomide-4'-acetamido-O-PEG2-C2-ClSOLU KNEX cleavable linker features a Val Ala dipeptide. In this product, a DBCO Dap(m PEG4) moiety replaces the conventional maleimidocaproyl (MC) unit to enhance aqueous solubility. DBCO is a strained alkyne commonly used in copper free click chemistry, specifically in the strain promoted azide alkyne cycloaddition (SPAAC) reaction. Derived from established ADC linker architectures, SOLU KNEX ADC linkers integrate solubilizing moietiessuch as PEG,
