33103998-9	2020	Among them, inhibition of N-glycan biosynthesis enhanced Spike-protein proteolysis.	n-glycan	26-34	surface glycoprotein	Severe acute respiratory syndrome coronavirus 2	57-62	
33657316-1	2021	The heterogeneity associated with glycosylation of the 66 N-glycan sites on the protein trimer making up the spike (S) region of the SARS-CoV-2 virus has been assessed by charge detection mass spectrometry (CDMS).	n-glycan	58-66	surface glycoprotein	Severe acute respiratory syndrome coronavirus 2	109-114	
33064451-7	2020	In addition, we compared N-glycan profiles of the recombinant spike proteins produced from different expression systems, including human embryonic kidney (HEK 293) cells and Spodoptera frugiperda (SF9) insect cells.	n-glycan	25-33	surface glycoprotein	Severe acute respiratory syndrome coronavirus 2	62-67	
34375000-2	2021	The 22 N-glycan sites of Spike remain highly conserved among SARS-CoV-2 variants, opening an avenue for robust therapeutic intervention.	n-glycan	7-15	surface glycoprotein	Severe acute respiratory syndrome coronavirus 2	25-30	
35436443-0	2022	35B5 antibody potently neutralizes SARS-CoV-2 Omicron by disrupting the N-glycan switch via a conserved spike epitope.	n-glycan	72-80	surface glycoprotein	Severe acute respiratory syndrome coronavirus 2	104-109
