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.
One of the major constraints to performing large-scale transfections of cultured mammalian cells for the transient expression of recombinant proteins is the production of large quantities of purified plasmid DNA. In this report partially purified plasmid D ...
Recent advances in the fields of biotechnology and medicine have intensified the necessity for pharmaceutical-grade biomacromolecules purification (e.g. enzymes, antibodies, plasmid DNA). One of the key factors for a successful downstream process is the po ...
We developed standard curves based on plasmids containing a 16S rRNA gene of a member of one of the three genera Dehalobacter, Desulfitobacterium, and Dehalococcoides. A large difference in amplification efficiency between the standard curves was observed ...
In the early events of human immunodeficiency virus type 1 (HIV-1) infection, immature dendritic cells (DCs) expressing the DC-specific intercellular adhesion molecule 3-grabbing nonintegrin (DC-SIGN) receptor capture small amounts of HIV-1 on mucosal surf ...
Regulation of the expression of MCT1 and MCT2, two isoforms of the monocarboxylate transporter (MCT) family, was investigated in primary cultures of mouse cortical neurons. Under basal conditions, both MCT immunoreactivities (IR) were found in the cell som ...
RNA interference has emerged as a powerful technique to downregulate the expression of specific genes in cells and in animals, thus opening new perspectives in fields ranging from developmental genetics to molecular therapeutics. Here, we describe a method ...
Tumor angiogenesis is a rate-limiting factor for tumor growth, and the endothelial cells of tumor vessels display specific features that can be exploited for the selective delivery of cancer therapeutics. To specifically target exogenous genes to angiogeni ...
Calcium phosphate transfection is a widely used method to produce recombinant proteins in mammalian cells. However, the mechanisms involved in plasmid DNA transfer to the nucleus of the transfected cells remain poorly understood and result in great variati ...
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 ...
RNA interference (RNAi) is a form of posttranscriptional gene silencing mediated by short double-stranded RNA, known as small interfering RNA (siRNA). These siRNAs are capable of binding to a specific mRNA sequence and causing its degradation. The recent d ...
