The reagent contains a bicyclo[6.1.0]nonyne (BCN) group that reacts with azides via strain-promoted alkyne-azide cycloaddition (SPAAC), enabling copper-free click chemistry in aqueous conditions.
- Non-cleavable four-unit PEG linker suitable for ADC construction.
- Enables strain-promoted alkyne-azide cycloaddition with azide-functionalized molecules.
- High reported purity for reliable conjugation performance.
- Available in multiple pack sizes, including small research quantities.
