Fig. 2From: Integrating transcriptomics, glycomics and glycoproteomics to characterize hepatitis B virus-associated hepatocellular carcinomaMALDI-TOF/TOF–MS spectra of N-glycans in HC, CHB, LC and HBV-HCC serum samples. Peaks of MALDI-TOF/TOF–MS spectra (signal-to-noise ratio > 5) were selected for relative intensity analysis in HC (A), CHB (B), LC (C) and HBV-HCC (D) samples. Detailed structures were annotated with GlycoWorkbench software. Proposed structures are indicated by m/z valueBack to article page
