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.
Biological cells continuously change shape allowing essential functions such as cell motility, vesicle-mediated release/uptake of soluble and membrane components or nanotube-mediated cell–cell communications. Here we use single cell micromanipulation to in ...
To explore the real-time dynamic behavior of molecular transporters of the cell-penetrating-peptide (CPP) type on a biological membrane, single fluorescently labeled oligoarginine conjugates were imaged interacting with the plasma membrane of Chinese hamst ...
We describe an optical method capable of tracking a single fluorescent molecule with a flexible choice of high spatial accuracy (~10–20 nm standard deviation or ~20–40 nm full-width-at-half-maximum) and temporal resolution (< 1 ms). The fluorescence signal ...
Recent developments in single-molecule localization techniques using photoactivatable fluorescent proteins have allowed the probing of single-molecule motion in a living cell with high specificity, millisecond time resolution, and nanometer spatial resolut ...
The role of calcium in signal transduction relies on the precise spatial and temporal control of its concentration. The existing means to detect fluctuations in Ca2+ concentrations with adequate temporal and spatial resolution are limited. We introduce her ...
We introduce here a new class of BODIPY-based Ca2+ indicators which can be derivatized with biological ligands that permit the localization of the indicators in living cells. The underivatized BODIPY-based Ca2+ indicator (BOCA-1) shows a 250-fold increase ...
Numerous synthetic fluorophores have been developed that can switch their spectroscopic properties upon interaction with other molecules or by irradiation with light. In recent years, protein-labeling techniques have been introduced that permit the specifi ...
The present invention relates proteins from the group consisting of CNNM1, CNNM2, CNNM 3 and CNNM4, its derivatives or fragments thereof for use as a medicament, for treatment and or diagnostic purposes. The invention further relates to a human genomic DNA ...
The plasma membrane defines the boundary of every living cell, and its integrity is essential for life. The plasma membrane may, however, be challenged by mechanical stress or pore-forming proteins produced by the organism itself or invading pathogens. We ...
Manganese (Mn) toxicity in humans has been observed as manganism, a disease that resembles Parkinson's disease. The mechanism of Mn toxicity and the chemical forms that may be responsible for its neurotoxicity are not well understood. We examined the toxic ...
