AMPA receptor imaging by infrared scanning near-field optical microscopy

Giorgio Margaritondo, Kai Johnsson, Harald Hirling, Johanna Generosi, Michel Kropf

Infrared scanning near-field optical microscopy is used to detect AMPA-type glutamate receptor clusters in hippocampal neuron cells. AMPA's GluR2-subunits were marked with the fluorophore Alexa488 and high-resolution micrographs were taken at 6.25 µm wavel ...

Photobleaching-free infrared near-field microscopy localizes molecules in neurons

Giorgio Margaritondo, Kai Johnsson, Harald Hirling, Johanna Generosi, Michel Kropf

High-resolution detection of specific molecules in cells is a major challenge in biology. We show that infrared scanning near-field microscopy can detect the spatial distribution of alpha-amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid–type glutamate r ...

Imaging of AMPA-type glutamate receptors in hippocampal neurons

Michel Kropf

Synaptic plasticity is the ability of the connections between nerve cells, called synapses, to change in strength. The presence of a-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA)-type glutamate receptors (AMPAR) at the synapse controls the str ...
