O-glycan analysis is a powerful analytical technique for qualitative and quantitative studies of O-glycosylation modifications in biopharmaceutical glycoproteins. This analysis technique can be used to determine the O-glycan structural composition and molecular content of protein drugs or other biological agents, and it can complete the analysis of the molecular structure of biopharmaceutical glycoproteins and the determination of free O-glycans. o glycan https://www.creative-proteomics.com/pronalyse/o-glycans-profiling.html
