Photonic Imaging Facility (I2PS)

The Cellular Imaging Facility offers imaging techniques from the sub-cellular level to the scale of the organism, as well as flow cytometry. 6 engineers (2 IR-CNRS, 1IR-SU, 2 IE-CNRS and 1IE-INSERM, 20%) ensure the maintenance and quality control of the equipment, the training and support of users as well as the technological and methodological development and scientific animation.

The Cellular Imaging facility provides access to a large variety of optical instruments (several confocal microscopes, including 2 coupled to a Becker & Hickl FLIM module, spinning disc/ILAS II microscope, TIRF/video microscope, light sheet microscope, multiphoton microscope, macro-apotome, multilaser analyzers).

The facility's investments were possible thanks to strong support from the CNRS, Sorbonne-University, the Île-de-France Region and GIS-IBISA, as well as from multiple teams and laboratories.

The facility proposes new imaging and flow cytometry methods (F-techniques, FLIM, 3D imaging, spectral imaging, life imaging, multicolor analysis) in collaboration with research groups, and puts its expertise at the service of the entire scientific community.

Jean-François Gilles was awarded the CNRS Cristal Medal for his development of a plugin, Distance analysis (DiAna), for the ImageJ software dedicated to image processing and analysis for biomedical research.

DiAna, which can be used with images informed on the basis of metadata, and which also integrates options for the segmentation of objects, is a response to a strong need of the international scientific community since it makes it possible to calculate the spatial colocalization of 3D objects and measure the distance between them.

New Materials

Two brandnew ZEISS 980 Airyscan II confocals coupled to fluorescence lifetime imaging have arrived at the facility.

Acknowledgement of imaging facility in your publications

It is COMPULSORY to acknowledge the imaging facility in your publications if you present data that has been produced with the help of facility equipment or personnel. If the participation of an engineer is décisive you should consider co-authorship.

The development of the imagine facility is possible du to funding by several sources. In order to acknowledge the facility and the personnel the following phrase must be used every time you publish work including equipment and/or the help of engineers:

Image acquisition and/or image analysis were performed at the IBPS Imaging Facility the authors greatly acknowledge ________ of the IBPS Imaging Facility. The IBPS Imaging facility is supported by Region-Île-de-France, Sorbonne-University and CNRS.

Thank you to indicate accepted papers to the staff, wee need them for our record to the sponsors/donors.
