Acetylcholine Receptor Organization in Membrane Domains in Muscle Cells: EVIDENCE FOR RAPSYN-INDEPENDENT AND RAPSYN-DEPENDENT MECHANISMS

Horst Vogel, Rudolf Hovius, Jean-Manuel Segura, Joachim Piguet, Christoph Schreiter

Nicotinic acetylcholine receptors (nAChR) in muscle fibers are densely packed in the postsynaptic region at the neuromuscular junction. Rapsyn plays a central role in directing and clustering nAChR during cellular differentiation and neuromuscular junction ...

Micropositioning and microscopic observation of individual picoliter-sized containers within SU-8 microchannels

Jürgen Brugger, Horst Vogel, Christoph Schreiter

We describe the fabrication and application of a bioanalytical chip, made of SU-8 photoresist, comprising integrated, high aspect-ratio microfluidic channels, suitable to manipulate and investigate vesicles, cell fragments and biological cells. A central m ...

Micro- and nanostructured devices for investigating biomolecular interactions

Jürgen Brugger, Horst Vogel, Christian Santschi, Christophe Danelon, Jean-Baptiste Perez, Christoph Schreiter

Cell membrane receptors and ion channels are essential in many different cellular processes. To analyse the activity of membrane proteins in vesicles and biological cells, we fabricated micro- nanostructured chips, enabling the application of electrophysio ...

Determining a receptor-ligand interaction useful in e.g. drug screening involves repetitive application of reversibly binding fluorescent ligands with fast association-dissociation kinetics

Horst Vogel, Rudolf Hovius, Jean-Manuel Segura, Marinela Gjoni Boillat, Christoph Schreiter

NOVELTY - Determining a receptor-ligand interaction involves repeatedly contacting a cell comprising a receptor, with a ligand, of the receptor in which the ligand has a fluorescence labeling group and binds reversibly to the receptor under conditions in w ...

Electrophysiology and fluorescence microscopy of ligand-gated ion channels

Christoph Schreiter

The thesis presented here describes studies of ligand binding, function, and arrangement of ligand-gated ion channels in cell membranes. Fluorescence microscopy and the patch clamp technique are used to investigate the nicotinic acetylcholine receptor and ...

Reversible sequential-binding probe receptor-ligand interactions in single cells

Horst Vogel, Rudolf Hovius, Jean-Manuel Segura, Marinela Gjoni Boillat, Christoph Schreiter

With the reversible sequential (ReSeq) binding assay, we present a novel approach for the ultrasensitive profiling of receptor function in single living cells. This assay is based on the repetitive application of fluorescent ligands that have fast assocn.- ...
