Ovarian Cancer Biomarkers

Increasing levels


  • Increased levels of core fucosylated agalactosyl biantennary glycans and glycans containing sialyl Lewis X.
  • Increased levels of tri- and tetra-antennary N-glycans.
  • Increased levels of sialylated glycans and a small group of truncated glycans.
  • Glycan Standard 13C Biantennary A1(3) (Sial α-2,3)
  • Glycan Standard 13C Tetraantennary A4-G1a
  • Bis α-2,6-sialylated biantennary glycopeptide from egg yolk
  • Bis α-2,3-sialylated, galactosylated biantennary glycopeptide

Ovarian Cancer Biomarkers

Decreasing levels


  • Decreased levels of glycans containing a bisecting GlcNAc.
  • Decreased levels of several neutral glycans, including high-mannose-type glycans.
  • Bis α-2,3-sialylated, galactosylated biantennary glycopeptide
