Ganglioside (GG) separation by IMS according to the charge state, carbohydrate chain length, degree of sialylation and ceramide composition, led to the identification of no less than 160 distinct components [1], which represents 3 folds the number of structures identified before. The detected GGs and asialo-GGs were found characterized by a high heterogeneity in their ceramide and glycan compositions, encompassing up five Neu5Ac residues. The tumor was found dominated in equal and high proportions by GD3 and GT1 forms, with a particular incidence of C24:1 fatty acids in the ceramide.
