Description

• An amine reactive heterobifunctional crosslinker which contains a dibenzylcyclooctyne (DBCO) group for copper-free click chemistry applications
• The crosslinker can be used to label a variety of amine containing molecules such as proteins, biomolecules, or small molecules
• Once a protein or (bio)molecule is DBCO labeled, it can undergo a copper-free azide-alkyne cycloaddition reaction to form a stable triazole linkage with an azide labeled coupling partner
• Can be used to create diverse conjugates with the biorthogonal coupling between an alkyne and azide (supplied separately)
• The coupling or crosslinking procedure is typically done in two steps
  • First, a protein or amine containing molecule is labeled with a DBCO group and excess crosslinker is removed
  • Second, an azide containing moiety (prepared independently) is introduced into the same system as the DBCO moiety
  • Labeling occurs under biological conditions without the introduction of any additional reagents such as a copper catalyst
• Ragent readily dissolves in water-miscible solvents for dilution into aqueous reaction mixtures
• TFP esters are more hydrolytically stable than NHS esters
