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.
Predissocn. spectra were detd. for SF6-Ar clusters in a mol. beam by monitoring the decrease in a specific mass spectrometer signals induced by a tunable continuous-wave CO2 laser. A red shift occurs downstream from the nozzle as the gas expands and the cl ...
Two strains of minute virus of mice (MVM) show different host cell specificities. The prototype strain MVM(p) grows in fibroblasts, whereas the immunosuppressive variant MVM(i) grows in T lymphocytes. In this study, we have mapped on the viral genome a cel ...
We exposed simian virus 40-infected CV-1 monkey cells to the carcinogen N-acetoxy-acetylaminofluorene and monitored the removal of lesions from cellular DNA and from various regions of viral DNA. Exposure to 5.5 microM 3H-labeled carcinogen produced 20-80 ...
Two murine parvoviruses with genomic sequences differing only in 33 nucleotides (8 amino acids) in the region coding for the capsid proteins show different host cell specificities: MVMi grows in EL4 T lymphocytes and MVMp3 grows in A9 fibroblasts. In this ...
The on-line electrochemical tagging (EC-tagging) of cysteine residues in proteins during mass spectrometry is studied to probe the cysteine environment. Benzoquinone probes electrogenerated at a microspray electrode react with the thiol functions of the pr ...
A synthetic antibody phage library, (ETH-2) was screened against the MUC-1 peptide. Two standard methods were used, namely screening on immunotubes coated with the peptide antigen and on streptavidin-coated paramagnetic particles together with a biotinylat ...
The karyophilic properties of the HIV-1 nucleoprotein complex facilitate infection of nondividing cells such as macrophages and quiescent T lymphocytes, and allow the in vivo delivery of transgenes by HIV-derived retroviral vectors into terminally differen ...
TRIM5alpha is a restriction factor that limits infection of human cells by so-called N- but not B- or NB-tropic strains of murine leukemia virus (MLV). Here, we performed a mutation-based functional analysis of TRIM5alpha-mediated MLV restriction. Our resu ...
The importance of the virally encoded dUTPase for CAEV replication, invasiveness, pathogenesis, and genetic stability was investigated in goats infected by viruses with single point (DU-G) and deletion (DU-1) mutations of the dUTPase gene (DU gene). The DU ...
Simian virus 40 (SV40) can be disassembled under mild conditions by reducing disulfide bonds in the capsid and removing calcium ions. The nucleoprotein complexes formed, analyzed by electron microscopy, were circular and made up of 59 +/- 4 subunits, each ...
