Un metodo specifico e sensibile al fine di conoscere il profilo di espressione di antigeni glicosfingolipidi in organi e cellule immunitarie è descritto. Il metodo sfrutta la spettrometria di massa a trappola ionica consentendo graduale frammentazione delle molecole glicosfingolipidi per l'analisi strutturale rispetto agli standard sintetizzati chimicamente.
