DBCO-maleimide

DBCO-Maleimide is a sulfhydryl reactive reagent containing a maleimide group and a DBCO moiety. Maleimide group specifically and efficiently reacts with thiols to form thioether bonds. The low mass weight will add minimal spacer to modified molecules and will enable simple and efficient incorporation of DBCO moiety into cysteine-containing peptides or other thiol-containing biomolecules. DBCO is commonly used for copper-free Click Chemistry reactions.

Dbco-Maleimide is used in preparation of radioactive metal indicator-chelating peptide derivative-conjugated antibodies for medical imaging.

Maleimide functionalized cyclooctyne derivative for incorporation of the cyclooctyne moiety into thiol containing compounds or biomolecules. Cyclooctynes are useful in strain-promoted copper-free azide-alkyne cycloaddition reactions. This dibenzocyclooctyne will react with azide functionalized compounds or biomolecules without the need for a Cu(I) catalyst to result in a stable triazole linkage.

Applications Include:

• Protein-peptide conjugates
• Antibody-enzyme or antibody-drug conjugates
• Protein or peptide-oligonucleotide conjugates
• Surface modification
