DBCO-PEG4-SE Chemical Properties,Usage,Production

Description

DBCO-PEG4-NHS Ester is a click chemistry PEG reagent containing NHS ester that is able to react specifically and efficiently with primary amines (e.g. the side chain of lysine residues or aminosilane-coated surfaces) at neutral or slightly basic condition to form a covalent bond. The hydrophilic PEG spacer arm improves water solubility and provides a long and flexible connection that minimizes steric hindrance involved with ligation. DBCO is commonly used for copper-free Click Chemistry reactions.

Uses

Succinimidyl ester (NHS, amine reactive) functionalized cyclooctyne derivative for incorporation of the cyclooctyne moiety into amine containing compounds or biomolecules. Cyclooctynes are useful in strain-promoted copper-free click chemistry 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

reaction suitability

reaction type: click chemistry
reagent type: linker
