Healthy human serum N-glycan profiling reveals the influence of ethnic variation on the identified cancer-relevant glycan biomarkers

HPLC chromatogram showing quantitation of free sialic acids.
A) standard Neu5Gc and standard Neu5Ac, B) Neu5Ac derived from captured serum N-glycans. Neu5Ac: N-acetylneuraminic acid, Neu5Gc: N-glycolylneuraminic acid. CMAH: Cytidine monophosphate N-acetylneuraminic acid hydroxylase (enzyme that catalyzes conversion of Neu5Ac to Neu5Gc).
