Imaging


SPIM
A new microscope based on a light sheet excitation, the SPIM (Selective Plane Illumination Microscope), allows rapid optical sectioning in 3D and in depth on living samples and offers multi-views acquisition opening new perspectives in biological observation. This unique equipment is now available to the entire scientific community

MacroSPIM
The MacroSPIM, a macroscope based on a light sheet excitation, makes it possible after optical clearing to visualize tissues and whole organs by rapid in depth 3D optical sectioning. This novel approach offers multi-view acquisition possibilities and opens up new perspectives in biological observation. This unique equipment, based on developments carried out in Barcelona (IRB), is now made available to the entire scientific community by CERT.

Confocal biphotonique
Finally, CERT is also equipped with a biphotonic confocal microscope. The use of an infrared laser for the excitation using higher wavelengths than in conventional fluorescence microscopy allows to penetrate more deeply into living samples and thus allows 3D and deep acquisitions.




Confocal microscopy
CERT has a confocal bi-photonic AxioExaminer microscope (LSM 880 Zeiss) equipped with a pulsed Ti/Sa (Chohérent) laser (NLO) and 3 visible lasers.
Using the QUASAR technology, this microscope offers the great advantage of simultaneous spectral detection in a single scan. It is possible, in a single acquisition, without loss of time and without space-time shift, to acquire and perfectly separate more than 4 fluorochromes whose spectra overlap.
- This technology also makes it possible to eliminate autofluorescence signal generated by tissues.
- The NLO system also gives access to the second harmonic generation (SHG) signal, thus allowing to reveal the organization of collagen fibers of the extracellular matrix or the striations of skeletal muscles without labelling.
- This equipment also allows to perform 3D and 4D imaging in vivo in small animals.

Videomicroscopes, Biphotons, SPIM
Real-time microscopy consists of imaging living samples over time with cellular resolution while maintaining temperature and respiratory conditions compatible with the survival of the samples. Samples can be cell cultures or whole organisms (mice, fish, drosophila), including tissue explants and spheroids.
We propose a variety of equipment : videomicroscopes, Biphotons, SPIM, that are all capable of Real-Time imaging. These equipments are coupled with specific modules that control the survival parameters of the samples (thermostatic chambers, CO2, anesthesia, respiratory and small animal monitoring systems).
- providing advice in the development of multi-color panels,
- ensuring the training of users,
- assisting users in the analysis and interpretation of their results,
- assisting users in the implementation of research and development projects, in the form of collaboration.
