PEG-epoxide pegylates hydroxyl groups at a mild reactivity and is most effectively coupled at higher pH(8.5-9.5). The PEG-epoxide may also pegylate hydoxyl, amine, thiol groups. The PEG-epoxide shows excellent water stability at basic pH.

PEG-NPC also pegylates hydroxyl groups

PEG-isocyanate also pegylates hydroxyl groups yielding stable urethane linkage. However, its reactivity may be best exploited for pegylating non-peptide moieties such as drugs, hydroxyl-containing matrices for chromatography, and also to produce biocompatible surfaces.
