Cell Membranes Suspended Across Nanoaperture Arrays

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

The authors present a method for spreading large (> 100 mm2) cell membrane fragments across nanoapertures in planar supports. Electron-beam and focused-ion-beam lithog. were used to fabricate arrays of 50-600 nm diam. holes in free-standing silicon nitride ...

Supported cell-membrane sheets for functional fluorescence imaging of membrane proteins

Jean-Baptiste Perez, Horst Vogel, Jean-Manuel Segura

Cell-membrane sheets suitable for in-vitro functional fluorescence studies have been prepd. by direct detachment from cell membranes using poly-L-lysine-coated glass slides. The resulting transferred planar membranes conserve the compn. as well as most pro ...

Micro- and nanostructured devices for investigating biomolecular interactions

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

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 ...

Monitoring the Diffusion of Single Heterotrimeric G Proteins in Supported Cell-membrane Sheets Reveals their Partitioning into Microdomains

Jean-Baptiste Perez, Horst Vogel, Jean-Manuel Segura, Joachim Piguet

Supported cell-membrane sheets are promising in vitro systems to investigate the properties of membranes with native protein/lipid composition, in particular their sub-compartmentalization and the differential localization of proteins associated to them. W ...

Investigating molecular interactions of G protein coupled receptors by fluorescence techniques

Jean-Baptiste Perez

G Protein coupled receptors (GPCRs) constitute an abundant family of membrane proteins which play a central role in cellular signaling and are important targets for modern medicine. Despite intensive research, central questions of the molecular mechanism o ...
