Reflectron MALDI-TOF and MALDI TOF/TOF analysis of control and fucosidosis urines – Representative positive-ion (A) and negative-ion (E) MS spectra of control urine. Representative positive-ion (B) and negative-ion (F) MS spectra of urine from fucosidosis affected patients with positive-ion MS/MS spectra of m/z 504.2 and 1079.5 (C-D) and negative-ion MS/MS spectrum of m/z 1518.6 (G). Fucose (black triangle), N-acetylglucosamine (black squares), Mannose (grey circles), Galactose (open circles), Sialic acid (grey diamond), Asn (asparagine).
