Description

Application

Propargyl-N-hydroxysuccinimidyl ester may be used as a tool for identifying nucleophilic ligandable hotspots by chemoproteomic approaches.

Propargyl-NHS ester is an amine reactive reagent for derivatizing peptides, antibodies, amine coated surfaces etc, with a terminal alkyne. The alkyne can be reacted with an azide containing compound or biomolecule via copper catalyzed azide-alkyne click chemistry to yield a stable triazole linkage.
