TN36: Analysis of Exoglycosidase Digestions of N-Linked Oligosaccharides Using HPAE-PAD (Part C)

Instrument Type: IC

This technical note describes the use of exoglycosidases to obtain structural information about N-linked oligosaccharides commonly found in mammalian glycoproteins. HPAE-PAD is used to confirm the identity of the released monosaccharides, as well as the remaining di-, tri,- or oligosaccharides. Empirical rules used to predict oligosaccharide elution order are included in the last section of this technical note.

AN215: Separation of Asparagine-Linked (N-Linked) Oligosaccharides from Human Polyclonal IgG

Instrument Type: IC

This application note shows how the PA200 improves N-linked oligosaccharide separations. The PA200 is used to profile N-linked oligosaccharides released from human polyclonal IgG by the enzyme PNGase F or endoglycosidase H (Endo H). This note also shows how subsequent exoglycosidase digestions can be used to assist in understanding and identifying oligosaccharide structure.
