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.
