Examples of mobility-extracted, negative ion CID (transfer region) spectra of N-glycans from SFV derived from a mosquito cell line. (A) Man₈GlcNAc₂, (B) Man₇GlcNAc₂, (C) Man₃GlcNAc₂, and (D) fucosylated Man₃GlcNAc₂. Symbols used for the glycan structures are as defined in Figure 2. Ion nomenclature follows that proposed by Domon and Costello⁵⁸ with spectral interpretation as described by Harvey et al.^49,50
