Loss of Protein Tyr-phosphorylation During in vitro Storage of Human Erythrocytes: Impact on RBC Morphology

Gerardo Turcatti, Niels Erik Lion, Benjamin Rappaz, Pierre Marquet, Michel Prudent

Wiley-Blackwell2014

Large scale inkjet-printing of carbon nanotubes electrodes for antioxidant assays in blood bags

Hubert Girault, Niels Erik Lion, Andreas Stephan Lesch, Fernando Cortes Salazar, Michel Prudent

Herein, we present the large scale fabrication of carbon nanotubes (CNT) electrodes supported on flexible polymeric sheets by subsequent multilayer inkjet printing of a silver layer for electrical connection, CNT layers as active electrode material and an ...

Elucidating the role of C-terminal post-translational modifications using protein semisynthesis strategies: α-synuclein phosphorylation at tyrosine 125

Hilal Lashuel, Michel Prudent, Bruno Claude Daniel Fauvet, Mirva Hejjaoui, Filip Vercruysse, Yao Zhang

Despite increasing evidence that supports the role of different post-translational modifications (PTMs) in modulating α-synuclein (α-syn) aggregation and toxicity, relatively little is known about the functional consequences of each modification and whethe ...

Phosphorylation of alpha-Synuclein at Y125 and S129 Alters Its Metal Binding Properties: Implications for Understanding the Role of alpha-Synuclein in the Pathogenesis of Parkinson's Disease and Related Disorders

Hubert Girault, Hilal Lashuel, Michel Prudent, Bruno Claude Daniel Fauvet, Yu Lu

alpha-Synuclein (alpha-syn) is a 140-amino acid protein that plays a central role in the pathogenesis of Parkinson's disease (PD) and other synucleinopathies. However, the molecular determinants that are responsible for triggering and/or propagating alpha- ...

Electrochemical reactions and ionization processes

Hubert Girault, Niels Erik Lion, Liang Qiao, Michel Prudent, Hongyan Bi, Mélanie Abonnenc

Electrochemical or photo-electrochemical reactions in both electrospray ionization and laser desorption ionization are discussed stressing the role of the electrode reaction in influencing the ionization process. In particular, upon application of a high v ...

Copper(I) and copper(II) binding to β-amyloid 16 (Aβ16) studied by electrospray ionization mass spectrometry

Hubert Girault, Liang Qiao, Michel Prudent, Yu Lu

Copper-b-amyloid 16 (Aβ16) complexes were investigated by electrospray ionization mass spectrometry (ESI-MS). Copper(I) and (II) complexes were formed on-line in a microchip electrospray emitter by using a sacrificial copper electrode as the anode in posit ...

Formation and study of single metal ion–phospholipid complexes in biphasic electrospray ionization mass spectrometry

Hubert Girault, Daniel Filipe Dos Santos Alves Jana, Anne-Clémence Corminboeuf, Manuel Alejandro Méndez Agudelo, Michel Prudent

Single metal ion-phospholipid complexes are observed in biphasic electrospray ionization mass spectrometry (BESI-MS) using a dual-channel microsprayer. Such a microsprayer makes it possible to put into contact two immiscible liquids within the Taylor cone. ...

Functional Electrospray Emitters

Hubert Girault, Michel Prudent

Electrospray ionisation (ESI) is a soft technique used in mass spectrometry (MS) analysis able to introduce a wide variety of analytes in the gas phase. Briefly, it consists in the application of a high- voltage to a solution to spray it through a small or ...

Plate for matrix-assisted laser desorption ionization mass spectrometry, comprises electroconductive substrate covered with sintered nanoparticles, deposited as array of spots, for supporting ionization of sorbed sample molecules

Hubert Girault, Niels Erik Lion, Christophe Roussel, Liang Qiao, Michel Prudent, Jingjing Wan

NOVELTY - A plate comprises an electroconductive substrate (1) at least partially covered with sintered nanoparticles (2), deposited as an array of individual spots, for use as a sorbing phase for a sample, and for supporting ionization of sorbed sample mo ...

The role of copper in cysteine oxidation: study of intra- and inter-molecular reactions in mass spectrometry

Hubert Girault, Michel Prudent

Cysteine-containing peptide oxidation was studied both by using an inert platinum electrode and a sacrificial electrode (copper or zinc) generating metallic ions in electrospray ionization mass spectrometry (ESI-MS). Using peptides containing one, two and ...
