DBCO-PEG4-DBCO is a PEG analogue containing a reactive two DBCO groups and a hydrophilic PEG spacer arm. DBCO will react with azide-bearing compounds or biomolecules to form a stable triazole linkage without copper catalyst. The hydrophilic PEG spacer arm can increase water solubility and a membrane permability. References: Wang H, Tang L, Liu Y, Dobrucka IT, Dobrucki LW, Yin L, Cheng J.
