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.
It is well-known that crowded environments affect the stability of proteins, with strong biological and biotechnological implications; however, beyond this, crowding is also expected to affect the dynamic properties of proteins, an idea that is hard to pro ...
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 ...
One of the most prominent self-labeling tags is SNAP-tag. It is an in vitro evolution product of the human DNA repair protein O 6-alkylguanine-DNA alkyltransferase (hAGT) that reacts specifically with benzylguanine (BG) and benzylchloropyrimidine (CP) deri ...
The specific labeling of proteins with synthetic probes is a powerful approach to study protein function and protein tags have been widely used for this purpose. A well-established example for a self-labeling protein tag is SNAP-tag. It specifically reacts ...
Genetically encoded fluorescent sensor proteins offer the possibility to probe the concentration of key metabolites in living cells. The approaches currently used to generate such fluorescent sensor proteins lack generality, as they require a protein that ...
We present a fluorescence activation-coupled protein labeling (FAPL) method, which employs small-molecular probes that exhibit almost no basal fluorescence but acquire strong fluorescence upon covalent binding to tag-proteins. This method enables real-time ...
The SNAP-tag labeling technology provides a simple, robust, and versatile approach to the imaging of fusion proteins for a wide range of experimental applications. Owing to the specific and covalent nature of the labeling reaction, SNAP-tag is well suited ...
Background: Fluorescence loss in photobleaching (FLIP) is a widely used imaging technique, which provides information about protein dynamics in various cellular regions. In FLIP, a small cellular region is repeatedly illuminated by an intense laser pulse, ...
Simultaneous tracking of many thousands of individual particles in live cells is possible now with the advent of high-density superresolution imaging methods. We present an approach to extract local biophysical properties of cell-particle interaction from ...
Over the last decade, several protein tags have been developed for the specific and covalent labeling of fusion proteins with small organic probes. Among them, SNAP-tag has been used in many applications such as live cell imaging, protein microarrays and t ...
