Quantification of the mono- and bis- sialylated O-glycopeptides of HPX. Quantification of mono- (HexNAc-Hex-Neu5Ac and 2HexNAc-2Hex-2Neu5Ac) and bis- (HexNAc-Hex-2Neu5Ac and 2HexNAc-2Hex-3Neu5Ac) sialylated O-glycopeptides of HPX isolated from pooled plasma of healthy volunteers (white bars), cirrhotic (grey bars), and HCC (black bars) patients. Intensities of the peptides, doubly O-glycosylated at T1 and T6 (right side of the figure), are ×10 magnified. Results represent XIC of precursor ions normalized to an internal peptide of HPX and error bars represent analysis of two different plasma pools (samples of five participants in each pool) as described in “Patients, materials and methods” section
