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.
The efficiency of selection for catalysis by phage display library was studied using a ligase (the Escherichia coli biotin ligase BirA) and an endopeptidase (the rat trypsin His57->Ala mutant) as model enzymes. These enzymes could be displayed on phage as ...
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 ...
Sequential stages in the life cycle of the ionotropic 5-HT3 receptor (5-HT3R) were resolved temporally and spatially in live cells by multicolor fluorescence confocal microscopy. The insertion of the enhanced cyan fluorescent protein into the large intrace ...
The oral delivery of protein and peptide drugs is limited by their proteolytic degradation and the poor absorption across the intestinal epithelia. In this work, we exposed a phage library of small bicyclic peptides (
Phage selections with combinatorial libraries of uniformly sized bicyclic peptides have recently yielded potent and selective binders of several protein targets. In this work we varied in a combinatorial fashion the ring sizes of bicyclic peptides in phage ...
Molecules with tailored binding specificities are needed for many purposes such as the development of therapeutics, the detection and purification of biomolecules or in chemical biology for the study and manipulation of biological systems. With phage displ ...
Bicyclic peptides binding to targets of interest can be isolated from combinatorial libraries using a phage display-based approach. In a first project of this thesis, we aimed at generating bicyclic peptide inhibitors of matrix metalloproteinases (MMPs), a ...
Bacteriophages with contractile tails epitomize the concepts of "virus" and "phage" for many because the tails of these phages undergo a large conformational change - resembling the action of a syringe - upon the attachment to the host cell. The contractil ...
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 ...
Cyclic peptides have a range of properties that make them attractive as therapeutics such as high binding affinity, good target selectivity and low toxicity. While most peptides in the clinic are derived from nature, various powerful in vitro evolution tec ...
