In this drop-down list, you will find the various equipment that make up the IMA’CRI platform:
Confocal Zeiss LSM 780 Airyscan
The Zeiss LSM 780 inverted confocal microscope, controlled by ZEN software and equipped with a thermostatic chamber, is fully motorized and enables sub-cellular observation of fixed samples or living cells. The microscope is equipped with a spectral strip for simultaneous observation of up to 8 colors, and a high-resolution detector to improve resolution by a factor of 1.7.

Software for image analysis
Imaris is a 3D/4D reconstruction software package published by Bitplane. It can be used to visualize images taken using photonic microscopy, by volume and surface reconstruction. It is freely available on the Plate-Forme after reservation on the CRI resources site.
Fiji is very comprehensive for image analysis (co-location, stack processing, colorimetry, edge search, segmentation, z projection, overlay, filters, 3D, .AVI .GIF animation creation, 3D deconvolution, …) and allows you to create macros.

X Clarity Biologos
X-CLARITY ™ systems and reagents standardize, simplify and accelerate every step of the tissue cleaning process. With the CLARITY method, preserved tissue is embedded in a hydrogel matrix and lipids are actively extracted by electrophoresis to create a stable, optically transparent tissue-hydrogel hybrid that is chemically accessible for multiple cycles of antibody labeling and imaging. Native cytoarchitecture remains intact and even endogenous fluorescence proteins are preserved for robust downstream fluorescence imaging.
