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.
This is the first report of two successful 100 l scale transienttransfections in a standard stirred bioreactor. More than half a gram of a monoclonal antibody (IgG) were produced in less than 10 days using a technology called large-scale transient gene exp ...
We describe the molecular cloning of the human transferrin receptor gene by a gene transfer approach. Mouse Ltk- cells were cotransformed with the herpes simplex thymidine kinase gene and total human DNA. Transformants expressing human transferrin receptor ...
BACKGROUND: Genetically engineered dendritic cells (DC) presenting specific antigens to T cells may be of great interest for immunotherapy. For this reason, the production of transgene-expressing DC derived from CD34 + cells transduced either shortly after ...
Human papillomavirus type 18 (HPV18) capsid proteins L1 and L2, synthesised in mammalian cells using recombinant vaccinia viral expression vectors, are transported to the nucleus and assembled into virus-like particles. When 293T cells, which express SV40 ...
The chromosomal locations, amounts, and level of expression of transfected, amplified c-myc and dihydrofolate reductase sequences were measured in cells cultured in the presence and absence of methotrexate. These studies show that the location and amount o ...
Using flow cytometry, single cell sorting, confocal microscopy and fluorescent plasmids, a thorough study of DNA uptake, DNA fate and DNA expression in mammalian cells transfected with the widely used calcium-phosphate precipitation method was executed. We ...
PURPOSE: To investigate the potential use of polymeric nanoparticles for the delivery of antisense oligonucleotides in HIV-1-infected cell cultures. METHODS: Phosphorothioate oligonucleotides were encapsulated into poly (D,L-lactic acid) nanoparticles. Two ...
