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.
In this study a novel approach for the coating and functionalization of substrates for cell culture and tissue engineering is presented. Glass, silicon, and titanium panes were coated with an ultrathin film (30 ± 5 nm) of reactive star-shaped poly(ethylene ...
Particle size should be optimized to achieve targeted and extended drug delivery to the affected tissues. We describe here the effects of the mean particle size on the pharmacokinetics and photothrombic activity of meso-tetra(carboxyphenyl)porphyrin (TCPP) ...
We describe an approach to the cloning of cell surface proteins that is independent of messenger RNA isolation. Mouse Ltk- cells are cotransformed with the thymidine kinase gene from Herpes Simplex Virus and total human DNA. Transformants expressing the hu ...
Culturing and comparing the discrete stages of tumorigenesis provide a route to defining important components of the cancer phenotype and, in addition, present the opportunity to establish cell cultures more representative of normal cells than the ultimate ...
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 ...
Superparamagnetic iron oxide nanoparticles (SPION) were coated with either Polyvinyl alcohol (PVA) or Vinyl alcohol/vinyl amine copolymer and further functionalized with the fluorochromes Cy3.5 or Texas Red. A colloidally stable suspension of nanoparticles ...
We present a new approach for biomass assessment in cell culture using a disposable microcentrifuge tube. The specially designed tube is fitted with an upper chamber for sample loading and a lower 5 microL capillary for cell collection during centrifugatio ...
Neurotrophic factors hold promise for the treatment of neurodegenerative diseases. Intrathecal transplantation of polymer encapsulated cell lines genetically engineered to release neurotrophic factors provides a means to deliver them continuously behind th ...
The cytoplasmic domain of transferrin receptor (TR) is essential for endocytosis of this transmembrane protein. We have investigated by electron microscopy the association of wild-type and cytoplasmic deletion mutant human TR with coated pits at the surfac ...
Stimulation of the macrophage-like cell line THP-1 with the phorbol ester phorbol 12-myristate 13-acetate (PMA) resulted in differentiation into cells with many features of macrophages. This differentiation was accompanied by transcriptional activation of ...
