Fig 1. LC-ESI-MS spectra of O-linked oligosaccharides from mucinous and serous cyst fluids.

Fig 1

Oligosaccharides was released by reductive β-elimination from acidic glycoproteins secreted into ovarian cyst fluids obtained from patients with high- and low-grade mucinous (A,B) and serous (C,D) OEC. Combined spectra of components eluted in the region 14–35 minutes in the chromatogram. Only major peaks identified are indicated. For all identified structures see S1 and S2 Tables. Fig 1A shows high abundant structures in low grade mucinous samples that are terminating with blood group O/H and blood group A, while structures in high grade mucinous (Fig 1B) as well as both low and high grade serous samples are terminating with sialic acid. *N-linked oligosaccharides also observed in the spectra.
