EEG-MEG evidence for early differential repetition effects for fearful, happy and neutral faces

To deter-mine how emotional information modulates subsequent traces for repeated stimuli, we combined simultaneous electro-encephalography (EEG) and magneto-encephalography (MEG) measures during long-lag incidental repetition of fearful, happy, and neutral ...

A new method for protein labeling with small molecules based on acyl carrier protein

Nathalie George

A new method for the covalent and specific labeling of fusion proteins of carrier proteins (CPs) with small organic molecules has been developed in this work. This technology combines the convenience of expressing genetically tagged reporter proteins with ...

FRET imaging reveals that functional neurokinin-1 receptors are monomeric and reside in membrane microdomains of live cells

Rudolf Hovius, Horst Vogel, Jean-Manuel Segura, Kai Johnsson, Nathalie George

The lateral organization of a prototypical G protein-coupled receptor, the neurokinin-1 receptor (NK1R), was investigated in living cells by fluorescence resonance energy transfer (FRET) microscopy, taking advantage of the recently developed acyl carrier p ...

Covalent labeling of cell-surface proteins for in-vivo FRET studies

Rudolf Hovius, Horst Vogel, Jean-Manuel Segura, Kai Johnsson, Bruno Meyer, Nathalie George, Pedro Pascoal

Fluorescence resonance energy transfer (FRET) is a powerful technique to reveal interactions between membrane proteins in live cells. Fluorescence labeling for FRET is typically performed by fusion with fluorescent proteins (FP) with the drawbacks of a lim ...

Multicolor Imaging of Cell Surface Proteins

Kai Johnsson, Nathalie George

The authors report on a method for the multicolor imaging of cell surface proteins which is based on the labeling of carrier protein (CP) fusion proteins with different fluorophores. In one application, different generations of a cell surface protein can b ...
