Propargyl-PEG2-acid is a linker consisting of propargyl and carboxylic acid functional groups. In the presence of activators (e.g. EDC, or HATU), the carboxylic acid reacts with primary amine to form a stable amide bond. The propargyl group reacts with azide group in biomolecules to yield a stable triazole linkage. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
