Mal-Lys(m-PEG4)-Gly-Gly-Phe-Gly-PAB-PNP Size:25mg Product Name Mal-Propionyl-PEG4-Val-Ala-PAB(m-PEG4)-Exatecan Synonyms CASSOLU KNEX cleavable linker features a Gly Gly Phe Gly (GGFG) peptide. In this product, a Mal Lys(m PEG4) moiety replaces the conventional maleimidocaproyl (MC) unit to enhance aqueous solubility. The PNP (para nitrophenyl) moiety serves as an activating leaving group, enabling efficient and selective conjugation of the payload to the linker. Derived from established ADC linker architectures, SOLU KNEX ADC linkers integrate solubilizing moietiessuch as
