Lectina coniugato perline POROS sono stati impiegati per HPLC. Standard glicopeptide serviti come controlli positivi e negativi. MARS-14 impoverito, tripsina-digerito plasmatiche umane è stato cromatografato e flow-through (FT) e le frazioni legato raccolti per analisi ESI-LC-MS/MS. Glicopeptidi sono stati arricchiti nella frazione legata, rispetto a FT.
