MS/MS spectra of the [M-2H]2- precursor of dermatan sulfate tetramer standard ΔHexA-GalNAc4S-IdoA-GalNAc4S-OH. (A) (top) CTD MS/MS spectrum (bottom) CTD MS/MS spectrum with resonance ejection. (B) Molecular structure inset represents fragmentation seen from both CTD and CTD with resonance ejection (black), CTD only (blue) and CTD with resonance ejection only (red). (C) Fragment type distribution for glycosidic, cross-ring, glycosidic sulfate loss and cross-ring sulfate loss fragment ions are shown.
