    Article Snippet: MF 874.3547 (9 μL) or standards (60 ng) of 4-nitrophenyl O -(N -acetyl-α-neuraminosyl)-(2-6)-β-d -galactopyranosyl-(1-4)-2-acetamido-2-deoxy-β-d -glucopyranoside (EN4614, Carbosynth Ltd., San Diego, CA), glycan-F58 (ULM-10078-CA, Cambridge Isotope Laboratories, Inc., Tewksbury, MA), and Sialo Anti-Proliferative Factor (GP131025, Sussex Research Laboratories, Ottawa, ON) were treated with α2-3 neuraminidase S (PO743S), α2-3,6,8 neuraminidase (#P0720S, New England Biolabs Inc., Ipswich, MA, USA), and O -glycosidase (#P0733S, New England Biolabs Inc.).

    Enzymatic deglycosylation and MS confirmation of core 1 glycosylation. MF 874.3547 untreated (A, C, E, G, I) and treated with α2-3,6,8 neuraminidase and O -glycosidase (B, D, F, H, J) were analyzed by LC-MS, and the spectra were evaluated by extracted ion chromatogram (EIC) for intact glycopeptide (A and B), the glycopeptide minus Neu5Ac (C and D), the Hex–HexNAc disaccharide (E and F), Neu5Ac (G and H), and the deglycosylated putative diamino acid S/TX (I and J). The * in panel C indicates a low level of the glycopeptide minus Neu5Ac ( m / z 584.2661) present in the undigested sample. Note the level of this product was considerably higher following digestion (G). In source fragmentation of SLC1G yielded the m / z 584.2661 product (# in panel C) at the same retention time as the undigested glycopeptide.

    Determining the position of the hexose on the isolated SGP. A The isolated SGP could be treated with pronase (top) to trim the peptide down to Asn or PNGase F (bottom) to remove the peptide completely. B The LC-MS chromatogram of pronase treated SGP, showing disappearance of the additional hexose. C ESI of the cleaved peptide from isolated SGP with PNGase F. The peak at 821 corresponds to the peptide with hexose.
