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.
An emerging model views gene regulation as a competition for regulatory sequences between transcription factors and nucleosomes at thermodynamic equilibrium. A computational model of the DNA affinity of nucleosomes was recently developed allowing to predic ...
The forthcoming arrival on the market of numerous protein therapeutics that require high clinical doses will foster the need for high-producing mammalian cell lines. Furthermore, pressures to reduce the development time for new therapeutics has meant more ...
Most tissue engineering approaches include the delivery of reparative cells to a damaged host tissue. Generally these cells are sought to be of a stem cell character since they retain a high potential for proliferation and differentiation into diverse phen ...
Gene transfer methods for producing recombinant cell lines are often not very efficient. One reason is that the recombinant DNA is delivered into the cell cytoplasm and only a small fraction reaches the nucleus. This chapter describes a method for microinj ...
The purpose of this review is to describe the current status and to highlight several emerging trends in the manufacture of recombinant therapeutic proteins in cultivated mammalian cells. focusing on Chinese hamster ovary cells as the major production host ...
Driven by the commercial success of recombinant biopharmaceuticals, there is an increasing demand for novel, cost-effective mammalian cell culture bioreactor systems for the production of biologicals requiring mammalian protein processing. Recently, orbita ...
The growing demand of biopharmaceutical products is boosting the market for therapeutic recombinant proteins (r-proteins). More than half of the 140 r-proteins that have gained approval for human therapeutic use are manufactured in mammalian cells that mak ...
Lentivirus-derived vectors (LVs) were studied for the generation of stable recombinant Chinese hamster ovary (CHO) cell lines. Stable pools and clones expressing the enhanced green fluorescent protein (eGFP) were selected via fluorescence-activated cell so ...
As primary lymphoid organ, the thymus provides the essential environment for maturation and selection of functional T lymphocytes. Thymic epithelial (TE) cells derive from the endoderm, and more specifically, from the third pharyngeal pouch. The thymic epi ...
Transfection with polyethylenimine (PEI) was evaluated as a method for the generation of recombinant Chinese hamster ovary (CHO DG44) cell lines by direct comparison with calcium phosphate-DNA coprecipitation (CaPO4) using both green fluorescent protein (G ...
