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.
First described about a decade ago, lentiviral vectors ('lentivectors') have emerged as potent and versatile tools of gene transfer for basic and applied research and offer exciting perspectives for the field of gene therapy. In the clinic, HIV-based vecto ...
Product isolation increasingly becomes a major bottleneck in molecular biotechnology. This is especially the case for the sensitive proteineous substances (recombinant proteins, antibodies) and lately also DNA, usually produced in low concentration. The cu ...
Over the course of evolution, retroviruses and their hosts have been in constant conflict, resulting in a long-term evolutionary "arms race" in which host and pathogen alternately gain selective advantages through functional innovations. On the host side, ...
Here we describe a phage strategy for the selection of ligands based on bicyclic or linear peptides attached covalently to an organic core. We designed peptide repertoires with three reactive cysteine residues, each spaced apart by several random amino aci ...
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 ...
Recently, a new method for the specific covalent labeling of fusion proteins in vitro and in living cells has been developed. This method is based on the unusual mechanism of a DNA repair protein: the O6-alkylguanine DNA alkyltransferase (AGT). In addition ...
Osteoarthritis (OA) is one of the most common causes of pain and disability. Currently, non-surgical treatment is limited to analgesic and anti-inflammatory drugs, which are not capable of either modifying the disease process or regenerate damaged parts in ...
Protein microarrays are an attractive approach for the high-throughput analysis of protein function, but their impact on proteomics has been limited by the technical difficulties associated with their generation. Here we demonstrate that fusion proteins of ...
A new method for the covalent and specific labeling of fusion proteins of carrier proteins (CPs) with small organic molecules has been developed in this work. This technology combines the convenience of expressing genetically tagged reporter proteins with ...
A review. Directed evolution consists of repetitive cycles of random mutagenesis of the protein/peptide sequence followed by screening or selection of candidates with desired properties. Many different approaches are used to introduce mutations into a gene ...
