Propargyl-PEG4-(CH2)3-CO2H is a linker containing a propargyl group at one end and a carboxylic acid at the other end. The carboxylic acid reacts with amine groups in the presence of activators (EDC or HATU). Under the catalyzation of copper, the propargyl group forms linkage with azide group of biomolecules. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

DBCO-PEG12-NHS Ester is a monodisperse PEG linker which enable free copper click chemistry with N3 group. NHS ester moiety can react specifically and efficiently with primary amines to form a covalent amide bond. The hydrophilic PEG spacer arm improves water solubility and provides a long and flexible connection that minimizes steric hindrance involved with ligation. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
