Azide-Lys(m-PEG4)-Gly-Gly-Phe-Gly-PAB(m-PEG4)-MMAE dacf1 Product Name Propargyl-Gly(m-PEG4)-Val-Cit-PAB(m-PEG8) Synonyms CASSOLU KNEX cleavable linker features a Gly Gly Phe Gly (GGFG) peptide. In this product, a Azide Lys(m PEG4) moiety replaces the conventional maleimidocaproyl (MC) unit to enhance aqueous solubility. The azide functional group is widely utilized in bioconjugation via click chemistry to enable efficient and selective attachment of biomolecules. Additionally, m PEG4 is attached to the commonly used self immolative para aminobenzyl (PAB) moiety to further
