Glycosylation profile of α- and β-chains from PMSG, eLH and human CG. In PMSG, O-aceylation on sialic acids was observed on both α- and β-chain. `S`-Sulfated N-glycans with polyLacNac were exclusively observed in horse luteinizing hormone. For human CG, bi- and tri-antenna N-glycans were observed in both α- and β-chain. All assignments were based on the biosynthesis pathway and previous studies.
