초록

PEGylated core-shell type resin (PEG-AM SURE) was developed by modifying the surface of AM SURE (TM) resin with diamino PEG. The conditions for the PEG coupling reaction were optimized by adjusting PEG chain cross-linking and the amount of free amino groups to ensure a enough loading level of functional groups on the resin (>0.30-0.39 mmol NH2/g). The resulting PEG-AM SURE resin showed better performance than conventional resins during solid-phase peptide synthesis of JR10-mer and beta 2m(58-69) 12-mer. (C) 2012 Elsevier Ltd.
