Azide-Dap(m-PEG4)-Val-Cit-PAB(m-PEG4)-PNP PEG4 707 SMILES OC(=O)CN1CCN(CC(O)=O)CCN(CC(=O)NCCCCCNC(=O)CCN2C(=O)C=CC2=O)CCN(CC(O)=O)CC1 Purity (HPLC)SOLU KNEX cleavable linker features a Val Cit dipeptide. In this product, a Azide Dap(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 increase
