  • This hetero-bifunctional reagent allows to crosslink alkyne (bio-)molecules to compounds bearing primary amines. The NHS ester group will react covalently with primary amines while the azide can undergo click reaction in catalyzed conditions with terminal alkynes. Thanks to the hydrophilic PEG spacer the compound is water soluble and thus treatment of biomolecules that treated in aqueous media is possible.
