Using Laser-Induced Rydberg Spectroscopy diagnostic for direct measurements of the local electric field in the edge region of NSTX/NSTX-U: Modeling

Luc Reymond

We discuss a novel diagnostic allowing direct measurements of the local electric field in the edge region of NSTX/NSTX-U. This laser based diagnostic's principle consists of depleting the naturally populated n = 3 level to a Rydberg state-sensitive to elec ...

Computational design of environmental sensors for the potent opioid fentanyl

Kai Johnsson, Luc Reymond

We describe the computational design of proteins that bind the potent analgesic fentanyl. Our approach employs a fast docking algorithm to find shape complementary ligand placement in protein scaffolds, followed by design of the surrounding residues to opt ...

Luciferases with tunable emission wavelengths

Kai Johnsson, Luc Reymond, Rudolf Griss, Alberto Schena, Qiuliyang Yu, Olivier Vincent Sallin, Lin Xue, Julien Hiblot, Nicholas Clarke Hill, Marina Daniela Beatrice Sabbadini

We introduce luciferases whose emission maxima can be tuned to different wavelengths by chemical labeling. These tunable luciferases are generated by inserting the small luciferase NanoLuc into the structures of the self-labeling proteins SNAP-tag or HaloT ...

Acetylated tubulin is essential for touch sensation in mice

Kai Johnsson, Luc Reymond, Antonino Asaro

At its most fundamental level, touch sensation requires the translation of mechanical energy into mechanosensitive ion channel opening, thereby generating electro-chemical signals. Our understanding of this process, especially how the cytoskeleton influenc ...

Sensors, methods and kits for detecting nicotinamide adenine dinucleotides

Kai Johnsson, Luc Reymond, Olivier Vincent Sallin

The invention relates to the in vitro and in cellulo detection of the cofactors nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP). Provided is a sensor molecule for fluorescence or luminescence-based detection o ...

Fluorogenic Probes for Multicolor Imaging in Living Cells

Kai Johnsson, Luc Reymond, Grazvydas Lukinavicius, Olivier Vincent Sallin, Keitaro Umezawa

Here we present a far-red, silicon-rhodamine-based fluorophore (SiR700) for live-cell multicolor imaging. SiR700 has excitation and emission maxima at 690 nm and 715 nm, respectively. SiR700-based probes for F-actin, microtubules, lysosomes and SNAP-tag ar ...

Genetic targeting of chemical indicators in vivo

Kai Johnsson, Luc Reymond, Antonino Asaro

Fluorescent protein reporters have become the mainstay for tracing cellular circuitry in vivo but are limited in their versatility. Here we generated Cre-dependent reporter mice expressing the Snap-tag to target synthetic indicators to cells. Snap-tag labe ...

SiR–Hoechst is a far-red DNA stain for live-cell nanoscopy

Kai Johnsson, Luc Reymond, Alberto Schena, Grazvydas Lukinavicius

Cell-permeable DNA stains are popular markers in live-cell imaging. Currently used DNA stains for live-cell imaging are either toxic, require illumination with blue light or are not compatible with super-resolution microscopy, thereby limiting their utilit ...

Reduced Dyes Enhance Single-Molecule Localization Density for Live Superresolution Imaging

Suliana Manley, Luc Reymond, Aleksandr Benke, Grazvydas Lukinavicius, Lina Carlini

Cell-permeable rhodamine dyes are reductively quenched by NaBH4 into a non-fluorescent leuco-rhodamine form. Quenching is reversible, and their fluorescence is recovered when the dyes are oxidized. In living cells, oxidation occurs spontaneously, and can r ...

A fluorogenic probe for SNAP-tagged plasma membrane proteins based on the solvatochromic molecule Nile Red

Kai Johnsson, Rudolf Hovius, Luc Reymond, Howard Riezman, Efthymia Prifti

A fluorogenic probe for plasma membrane proteins based on the dye Nile Red and SNAP-tag is introduced. It takes advantage of Nile Red, a solvatochromic molecule highly fluorescent in an apolar environment, such as cellular membranes, but almost dark in a p ...
