|Characterization of Gangliosides by Liquid Chromatography Coupled to MS/MS and MS/MS/MS|
Gangliosides are versatile molecules fulfilling numerous biological functions and their presence is crucial for the nervous system. The characterization of gangliosides by HPLC-MS enables the determination of the various head and tail group compositions. Employing HILIC (hydrophilic interaction liquid chromatography) results in the separation of gangliosides by their head group, whereas reversed-phase chromatography leads to differentiation according to the tail group composition.
This work was carried out in the group of Prof. Stefan Schürch.
