Analysis of Intact Monoclonal Antibody IgG1 by Electron Transfer Dissociation Orbitrap FTMS

Yury Tsybin, Luca Fornelli

The primary structural information of proteins employed as biotherapeutics is essential if one wishes to understand their structure-function relationship, as well as in the rational design of new therapeutics and for quality control. Given both the large s ...

Observation of ion coalescence in Orbitrap Fourier transform mass spectrometry

Yury Tsybin, Luca Fornelli

RATIONALE Similar to other mass spectrometric technologies based on ion trapping in a spatially restricted area, the performance of Orbitrap Fourier transform mass spectrometry (FTMS) is affected by the interaction between the trapped ion clouds. One of th ...

Glycan variability on a recombinant IgG antibody transiently produced in HEK-293E cells

Florian Maria Wurm, Yury Tsybin, Luca Fornelli, Lucia Baldi Unser, Sophie Nallet, Simone Schmitt, Julien Parra

In this study, a recombinant monoclonal IgG antibody was produced by transient gene expression (TGE) in suspension-adapted HEK-293E cells. The objective of the study was to determine the variation in recombinant IgG yield and glycosylation in ten independe ...

In-Spray Supercharging of Peptides and Proteins in Electrospray Ionization Mass Spectrometry

Hubert Girault, Yury Tsybin, Luca Fornelli, Yu Lu, Sasa Miladinovic, Krzysztof Marek Piech

Enhanced charging, or supercharging, of analytes in electrospray ionization mass spectrometry (ESI MS) facilitates high resolution MS by reducing an ion mass-to-charge (m/z) ratio, increasing tandem mass spectrometry (MS/MS) efficiency. ESI MS superchargin ...

Structural analysis of intact monoclonal antibodies by electron transfer dissociation mass spectrometry

Florian Maria Wurm, Yury Tsybin, Luca Fornelli, Sophie Nallet, Julien Parra

Improving qualitative and quantitative characterization of monoclonal antibodies is essential, because of their increasing popularity as therapeutic drug targets. Electron transfer dissociation (ETD)-based top-down mass spectrometry (MS) is the method of c ...

Deamidation and Transamidation of Substance P by Tissue Transglutaminase Revealed by Electron-Capture Dissociation Fourier Transform Mass Spectrometry (Chem. Eur. J. 2/2011)

Horst Vogel, Yury Tsybin, Luigino Grasso, Adrian Schmid, Luca Fornelli

Tissue transglutaminase (tTGase) catalyzes both deamidation and transamidation of peptides and proteins by using a peptidyl glutamine as primary substrate. A precise consensus sequence for the enzyme is unknown and the ratio between deamidated and transami ...
