Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

Much research has been dedicated to understanding the molecular basis of UV damage to biomolecules, yet many questions remain regarding the specific pathways involved. Here we describe a genome-mediated mechanism that causes sitespecific virus protein clea ...

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 ...

We decoupled electron-transfer dissociation (ETD) and collision-induced dissociation of charge-reduced species (CRCID) events to probe the lifetimes of intermediate radical species in ETD-based ion trap tandem mass spectrometry of peptides. Short-lived int ...

The conformations of a number of M2TMP-(22-46) sequence variants have been investigated using ion mobility spectrometry (IMS). Substantial conformational changes were evidenced by IMS upon the variation of a single amino acid in the peptide sequence, with ...

We report on the characteristics of the radical-ion-driven dissociation of a diverse array of beta-amino acids incorporated into alpha-peptides, as probed by tandem electron-capture and electron-transfer dissociation (ECD/ETD) mass spectrometry. The report ...

We present mechanistic studies aimed at improving the understanding of the product ion formation rules in electron capture dissociation (ECD) of peptides and proteins in Fourier transform ion cyclotron resonance mass spectrometry. In particular, we attempt ...

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 ...

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 ...

Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) has been used to probe the interaction of the anticancer drug cisplatin with oligonucleotides. The binding kinetics, the nature of the adducts formed, and the location of the binding s ...

Mass spectrometry techniques employing electron capture and electron transfer dissociation represent powerful approaches for the analysis of biological samples. Despite routine employment in analytical fields, the underlying physical processes dictating pe ...
