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.
The final glycosylation pattern of recombinant proteins might be determined by the choice of the host cell, cell culture conditions and the purification. Each step influences glycosylation and improved glycosylation of the product may thus be obtained by c ...
Tyrosine sulfation and O-glycosylation are two post-translational modifications playing an essential role in modulation of biol. activity, protein folding and cellular communication. Here, a novel chem. approach for the synthesis of biotinylated glycosulfo ...
Innate immune recognition of microbes is a complex process that can be influenced by both the host and the microbe. Drosophila uses two distinct immune signaling pathways, the Toll and immune deficiency (Imd) pathways, to respond to different classes of mi ...
An anti-Rhesus D antibody was produced in various cell-lines and cell-types which were either stable or transient transfected and grown under varying culture conditions. Glycosylation anal. of the IgG1 was carried out mainly by HPAEC methods. The antibody ...
Two sets of RNA phosphoramidites, carrying the (fluoride-labile) 2'-O-[(triisopropylsilyl)oxy]methyl (tom) group and the (photolabile) [(R)-1-(2-nitrophenyl)ethoxy]methyl ((R)-npeom) group, were prepd. The two protecting groups were completely orthogonal t ...
Sensitivity of mammalian cells to the bacterial toxin aerolysin is due to the presence at their surface of glycosylphosphatidyl inositol (GPI)-anchored proteins which act as receptors. Using a panel of mutants that are affected in the GPI biosynthetic path ...
Gpi8p and Gaa1p are essential components of the GPI transamidase that adds glycosylphosphatidylinositols (GPIs) to newly synthesized proteins. After solubilization in 1.5% digitonin and separation by blue native PAGE, Gpi8p is found in 430-650-kDa protein ...
Aerolysin is one of the major virulence factors produced by Aeromonas hydrophila, a human pathogen that produces deep wound infection and gastroenteritis. The toxin interacts with target mammalian cells by binding to the glycan core of glycosylphosphatidyl ...
The central reaction in the process of N-linked protein glycosylation in eukaryotic cells, the transfer of the oligosaccharide Glc(3)Man(9)GlcNAc(2) from the lipid dolicholpyrophosphate to selected asparagine residues, is catalyzed by the oligosaccharyltra ...
Currently two types of chip systems are used in conjunction with MS: out-of-plane devices, where hundreds of nozzles, nanospray emitters are integrated onto a single silicon substrate from which electrospray is established perpendicular to the substrate, a ...
