실험 절차

As depicted in above Scheme 2, 6-arm PEG (1) synthesized in the Scheme 1 is reacted with glutarate reagents, e.g., glutaric anhydride to synthesize 6-arm PEG-glutatic acid (6-arm PEG-GA) (2). The compound (2) was reacted with N-hydroxy succinimide (NHS) and N, N′-dicyclohexylcarbodiimide (DCC) to produce 6-arm PEG-succinimide glutarate (6-arm PEG-SG) (3).
