0]non-4-yne) is a strained cyclooctyne used in click chemistry for copper-free bioconjugation reactions

NRX-1532 is an enhancer of the interaction between beta-catenin and beta-TrCP

DBCO-Lys(m-PEG4)-Val-Cit-PAB(m-PEG4)-Exatecan Size:10mg Cy5 (Cyanine 5SOLU KNEX cleavable linker features a Val Cit dipeptide. In this product, a DBCO Lys(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
