MALDI/TOF mass spectra of gangliosides extracted from NSCLC tissues. (a) and (b) (upper): purified controls of NeuAcGM3 and NeuGcGM3 gangliosides, respectively. Lower parts of panels (a) and (b) correspond to extracted fraction of NeuAcGM3 and NeuGcGM3 after the routine histological procedures. (c) Amplification of the lower part of panel (b).
