Fig. 4From: Simultaneous analyses of N-linked and O-linked glycans of ovarian cancer cells using solid-phase chemoenzymatic methodMS/MS fragmentation of QUANTITY-tagged N-glycans. The N4H5S2 was extracted from OVCAR-3 cells and labeled by QUANTITY. MS/MS was performed by Thermo Orbitrap Mass Spectrometer. When a reporter is lost, the mass is reduced by 176–178 with a “Loss reporter”Back to article page
