Incremental model identification of gas-liquid reaction systems

Dominique Bonvin, Julien Léo Billeter, Sriniketh Srinivasan

Identification of kinetic models is an important task for monitoring, control and optimization of industrial processes. Kinetic models are often based on first principles, which describe the evolution of the states – numbers of moles, temperature and volum ...

Inactivation of bacteriophage MS2 with potassium ferrate(VI)

Tamar Kohn, Anne Thérèse Sigstam, Timothy Strathmann

Abstract - Ferrate [Fe(VI); FeO42-] is an emerging oxidizing agent capable of controlling chemical and microbial water contaminants. Here, inactivation of MS2 coliphage by Fe(VI) was examined. The inactivation kinetics observed in individual batch experime ...

On the utility of predictive chromatography to complement mass spectrometry based intact protein identification

Yury Tsybin, Hisham Ben Hamidane

The amino acid sequence determines the individual protein three-dimensional structure and its functioning in an organism. Therefore, "reading" a protein sequence and determining its changes due to mutations or post-translational modifications is one of the ...

Combination of Gas-Phase Fractionation and MS3 Acquisition Modes for Relative Protein Quantification with Isobaric Tagging

Loïc Dayon, Martin Kussmann

Relative quantification of peptides and proteins with isobaric tags such as iTRAQ or TMT is commonly used in comparative quantitative proteomics based on tandem mass spectrometry (MS/MS). Nonetheless, isobaric tagging inherently suffers from the cofragment ...

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 ...

Repeatability and reproducibility of product ion abundances in electron capture dissociation mass spectrometry of peptides

Yury Tsybin, Hisham Ben Hamidane, Aleksey Vorobyev

Site-specific reproducibility and repeatability of electron capture dissociation (ECD) in Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) are of fundamental importance for product ion abundance (PIA)-based peptide and protein struct ...

Peptide Structure and Radical Chemistry in the Gas Phase Revealed by Product Ion Abundance Analysis in Electron Capture and Transfer Dissociation Mass Spectrometry

Hisham Ben Hamidane

Peptide and protein ion abundances in mass spectrometry (MS) and tandem mass spectrometry (MS/MS) may provide orthogonal, or complementary, information to their mass measurements. Collision induced dissociation (CID), the most commonly used MS/MS technique ...

Switchable fluorophores for protein labeling in living cells

Kai Johnsson, Grazvydas Lukinavicius

Numerous synthetic fluorophores have been developed that can switch their spectroscopic properties upon interaction with other molecules or by irradiation with light. In recent years, protein-labeling techniques have been introduced that permit the specifi ...
