Member of C2RT (Center for Resources and Research in Technology) the Unit for service and technology in ultra-structural bio-imaging (UBI) at Pasteur provides technical and scientific support in electron microscopy, mainly, but not exclusively, to the Pasteur community, analyzing host-pathogen interactions at the ultra-structural level. Our equipment enables us to do state-of-the-art EM for life sciences that includes three dimensional EM by tomography and focused ion beam SEM. The ultrapole is run by ten members (eight engineers and two technicians), each specialized in certain techniques. We put a big emphasis on correlate light- and electron microscopy to study key (rare events) of host-pathogen interactions and we have designed several protocols to combine room temperature LM and cryo-LM with FIB-SEM, cryo-SEM and cryo-tomography.
The UBI also has a small research group focusing on large DNA-viruses. Through this research theme we wish to establish and develop robust, new protocols for various EM-techniques.
