Chattez avec Graph Search
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.
Proteomic studies require analytical methods capable of separating, identifying and quantifying thousands of proteins. Consequently, developing separation methodologies with high resolving power necessary to separate complex protein samples prior to protei ...
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 address the general question of the extent to which the hydrodynamic behaviour of microscopic freely fluctuating objects can be reproduced by macrosopic rigid objects. In particular, we compare the sedimentation speeds of knotted DNA molecules undergoin ...
A versatile microreactor protocol based on microfluidic droplets has been developed for on-line protein digestion. Proteins separated by liquid chromatography are fractionated in water-in-oil droplets and digested in sequence. The microfluidic reactor acts ...
Proteomics is nowadays one of the most important research topics in life science for understanding many life activities from the molecular level. The objective is to find out proteins or modifications on proteins that regulate biological events, aging, dis ...
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 ...
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 ...
Crowding and confinement can affect protein stability, favouring the more compact species amongst the folded and unfolded conformations. An unbiased assessment of the relative efficacy of crowded and confined environments has been hampered so far by the pa ...
Organic and biological macromolecules have attracted great interest within nanotechnology research due to properties that can be useful in future devices. Interesting functionalities such as optical activity, host-guest binding and molecular recognition ar ...
Electrospray ionization mass spectrometry (ESI-MS) is a powerful tool to investigate large molecules. Miniaturized microchips, as a goal of ‘Lab-on-chip’, allow various integrated analysis quickly. The coupling of functional microchips and ESI-MS is capabl ...
