Product Info
Propargyl-PEG4-CH2CO2-NHS has a propargyl group and an NHS group. This reagent is amine reactive, thus, useful for derivatizing biomolecules with amine group. The propargyl group reacts with azides via copper catalyzed azide-alkyne Click Chemistry to form stable triazole bond. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
