The QqQ mass spectrometer was operated in the precursor ion scanning of the characteristic fragment of GG, <i>N</i>-Acetylneuraminic acid, at <i>m/z</i> 290, in the negative ionization mode.</p> 2016-12-20 21:20:16 ganglioside species role GD retina LC GT novel research directions Tissue Specificities Gangliosides Other Ocular Structures
