Practical Considerations for Improving the Productivity of Mass Spectrometry-based Proteomics

Yury Tsybin, Anton Kozhinov, Luca Fornelli, Kristina Srzentic, Unige Anna Laskay, Oxana Upir

Mass spectrometry (MS) is currently the most sensitive and selective analytical technique for routine peptide and protein structure analysis. Top-down proteomics is based on tandem mass spectrometry (MS/MS) of intact proteins, where multiply charged precur ...

Dual-Channel Electrospray Microchip

Hubert Girault, Niels Erik Lion, Fang Liu, Yu Lu

A dual-channel electrospray microchip has been developed for electrospray ionization mass spectrometry (ESI-MS) where aqueous samples are mixed at the Taylor cone with an organic buffer. Due to the fast and effective mixing in the Taylor cone, the aqueous ...

Coupling Isoelectric Focusing Gel Electrophoresis to Mass Spectrometry by Electrostatic Spray Ionisation

Hubert Girault, Liang Qiao, Elena Tobolkina

Gel electrophoresis has been used for decades as a high-resolution separation technique for proteins and protein isomers, but limited in the coupling with MS because of low throughput and poor automaticity compared with LC-MS. In this work, we have develop ...

The herbicide glyphosate and its metabolite AMPA in the Lavaux vineyard area, western Switzerland: proof of widespread export to surface waters. Part I: Method validation in different water matrices

Dominique Grandjean, Luiz Felippe De Alencastro

An analytical method for the quantification of the widely used herbicide, glyphosate, its main by-product, aminomethylphosphonic acid (AMPA) and the herbicide glufosinate at trace level was developed and tested in different aqueous matrices. Their derivati ...

Principles of electron capture and transfer dissociation mass spectrometry applied to peptide and protein structure analysis

Yury Tsybin, Matthew Wodrich, Luca Fornelli, Konstantin Zhurov, Unige Anna Laskay

This tutorial review describes the principles and practices of electron capture and transfer dissociation (ECD/ETD or ExD) mass spectrometry (MS) employed for peptide and protein structure analysis. ExD MS relies on interactions between gas phase peptide o ...

Top-down analysis of 30–80 kDa proteins by electron transfer dissociation time-of-flight mass spectrometry

Yury Tsybin, Luca Fornelli, Julien Parra

Electron transfer dissociation (ETD)-based top-down mass spectrometry (MS) is the method of choice for in-depth structure characterization of large peptides, small- and medium-sized proteins, and non-covalent protein complexes. Here, we describe the perfor ...

Turbulent regimes in the tokamak scrape-off layer

Paolo Ricci, Joaquim Loizu Cisquella, Sébastien Jolliet, Federico David Halpern, Annamaria Mosetto

We identify the turbulent regimes in the tokamak scrape-off layer as a function of plasma resistivity, electron to ion mass ratio, safety factor, and magnetic shear. We find that two main instabilities drive turbulence in the SOL: Drift Waves, with their r ...

Evaluation of high-field Orbitrap Fourier transform mass spectrometer for petroleomics

Yury Tsybin, Anton Kozhinov, Konstantin Zhurov

The performance of the high-field Orbitrap Fourier transform mass spectrometer (FTMS) is evaluated in the context of petroleum sample analysis. Pertinent characteristics including resolving power, mass accuracy, and spectral dynamic range are tested with r ...
