The azido-dPEG®12-NHS ester contains an azide function on one end of a single molecular weight dPEG® spacer (47.2 Å) and NHS ester group on the other end of the spacer. The dPEG® spacer is hydrophilic and non-immunogenic and improves the water solubility of the target molecule while reducing the immunogenicity and increasing the hydrodynamic volume of the target. N-hydroxysuccinimide (NHS) ester readily reacts with amines in aqueous solution or organic solvent. The azide group reacts with an alkyne in the well-known click chemistry reaction. The click chemistry reaction proceeds by copper(I) or ruthenium catalysis or in a strain-catalyzed reaction with certain types of alkyne partners.
