Azide-Lys(m-PEG4)-Val-Cit-PAB(m-PEG8) carboxylic ester Product Name CP-SS-SulfoCy5 Synonyms SNAP2-SS-SulfoCynineSOLU KNEX cleavable linker features a Val Cit dipeptide. 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 PEG8 is attached to the commonly used self immolative para aminobenzyl (PAB) moiety to further increase
