Propargyl-NH-PEG3-C2-NHS ester

This non-cleavable linker, featuring propargyl and N-hydroxysuccinimide ester groups connected by a triethylene glycol spacer, is a key reagent for bioconjugation. It is widely used in ADC development and other biomedical research for creating stable, site-specific conjugates of biomolecules for both in vitro and in vivo applications.
