Bis-propargyl-PEG3 is a crosslinker with alkyne groups at both ends of the molecule. The alkyne groups react with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry to form a stable triazole linkage. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
