N-glycan is used as a standard for QC analysis of biopharmaceuticals. N-glycan analysis is an important biochemical technology for the research and development of biopharmaceuticals and the comparative research projects of biosimilars and innovative drugs. The technical method can be used to determine the characterization and analysis information of N-glycan sequence information of biopharmaceutical proteins or other biological agents, the connection mode of monosaccharide residues and the number of glycan isomers.
