Fig 8. MS/MS spectrum of N-200 glycopeptide from 21K slow prion strain.

Fig 8

The glycopeptide represented in the figure is the one carrying N-glycan with a composition H5N6S2F2. The usual fragments of glycan-specific marker ions are represented, additionally with a fragment of m/z value 495.1742 (1+), suggesting the presence of 6sLeC. Also, y ions confirming the amino acid sequence of the N-200 peptide and fragments of the peptide backbone with the N-glycan are visible. Blue square–N-acetylglucosamine (GlcNAc), green circle–mannose (Man), red triangle–fucose (Fuc), yellow circle–galactose (Gal), purple diamond–N-acetylneuraminic acid (Neu5Ac).
