A mixture of alginate and polyethylene glycol acrylate was investigated as a system for the encapsulation of islets of Langerhans. This system showed dual crosslinkability: the alginate was ionically crosslinked by multivalent cations, and the PEG was covalently crosslinked by

This paper describes synthesis of asparagine-linked sialylglycopeptides. The typical feature of our strategy for the synthesis of a sialylglycopeptide is to employ undecadisialyloligosaccharyl Fmoc-asparagine (Fmoc-Asn(CHO)-OH) 1 without protecting groups on its hydroxyl groups except for the benzyl ester of the
