DBCO-Dap(m-PEG4)-Val-Cit-PAB(m-PEG4)-PNP Size:50mg Product Name DOTA-PEG5-propargyl Synonyms CASSOLU KNEX cleavable linker features a Val Cit 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. Additionally, m PEG4 is attached to the commonly used self immolative para aminobenzyl (PAB) moiety to further
