Background/Objectives: Glycosylation can affect vaccine antigen structure and function, making site-specific glycan characterization relevant to antigen quality and comparability. However, quantitative approaches for comparing glycan microheterogeneity

Variation of Site-Specific Glycosylation Profiles of Recombinant Influenza Glycoproteins

August 9, 2024
Author(s)
Zachary Goecker, Meghan Burke Harris, Concepcion Remoroza, Yi Liu, Yuri Mirokhin, Sergey Sheetlin, Dmitrii V. Tchekhovskoi, Xiaoyu (Sara) Yang, Stephen E. Stein
This work presents a detailed determination of site-specific N-glycan distributions of the recombinant influenza glycoproteins hemagglutinin (HA) and neuraminidase. Variation in glycosylation among recombinant glycoproteins is not predictable and can

Comparison of N-glycopeptide to released N-glycan abundances and the influence of glycopeptide mass and charge state on N-linked glycosylation of IgG antibodies

March 7, 2024
Author(s)
Concepcion Remoroza, Meghan Burke Harris, Tytus Mak, Sergey Sheetlin, Yuri Mirokhin, Zachary Goecker, Brian T. Cooper, Mark Lowenthal, Xiaoyu (Sara) Yang, Guanghui Wang, Dmitrii V. Tchekhovskoi, Stephen E. Stein
We report the comparison of mass-spectral-based abundances of tryptic glycopeptides to fluorescence abundances of released labeled glycans and the effects of mass and charge state and in-source fragmentation on glycopeptide abundances. The primary
