Product Introduction
DBCO-PEG8-Mal is a heterobifunctional reagent featuring a dibenzocyclooctyne (DBCO) moiety and a maleimide group linked by an eight-unit polyethylene glycol (PEG) spacer. The DBCO functionality enables strain-promoted azide-alkyne cycloaddition (SPAAC) reactions, facilitating copper-free click chemistry applications, while the maleimide group is reactive towards thiol groups, allowing for efficient bioconjugation to cysteine residues. This reagent is commonly used in the modification of biomolecules, enabling dual-functionalization strategies for advanced labeling, surface modification, and polymer conjugation.
