FBI-AT 2022 – Description

The course will have plenary lectures given by experts in the microscopy development field. These seminars will be advertised as a series and will be broadcasted for a large audience.  In addition, specific techniques will be introduced.

Hands-on practicals will train attendants on these techniques every afternoon in different sites in Paris including Institut Curie, Institut Pasteur, Institut Cochin, Institut Jacques Monod, Institut de Psychiatrie et Neurosciences de Paris and ENS Paris. Access to this part of training will be restricted to selected and registered trainees.

To guaranty access to set-ups and proper training, each practical session will host only 3-4 persons. The sessions will be run in parallel.

Register now, attendance will be limited to 25 participants! 

FBI-AT is ideal for researchers with a basic training in microscopy willing to become familiar with advanced techniques to answer their specific biological questions, or to be exposed to new developments that will allow them to tackle new questions in their project. We will consider applications from early career researchers (PhD students, post-docs), technical staff members and more senior scientists.

[su_accordion][su_heading size=”24″ margin=”10″]Practical 1: Combining micro UV-irradiation and Single Particle Tracking in living cells[/su_heading]

[su_tabs active=”1″ vertical=”yes”][su_tab title=”Organisers”]Judith Miné-Hattab, David Mazaud, Patricia Le Baccon, Fabiola Garcia Fernandez[/su_tab] [su_tab title=”Description”]In this module, we will learn how to perform Single Particle Tracking (SPT), a powerful technique allowing the observation of individual molecules in living cells. We will learn: i) how to prepare samples, ii) how to perform the acquisition iii) and how to analyze trajectories of individual molecules. Moreover, we have combined our SPT system with a UV-laser micro irradiation module, allowing us to induce DNA damages and follow the dynamics of individual molecules as early as a few seconds after irradiation. We will use this module in human cells during the workshop.[/su_tab] [su_tab title=”Lectures”]

[su_tabs active=”1″ vertical=”yes”][su_tab title=”Organisers”]Thomas Guilbert, Julie Lesieur, Pierre Bourdoncle, IMAG’IC Institut Cochin[/su_tab] [su_tab title=”Description”]In this module, we will have a look on how to explore thick tissues with multiphoton microscopy. The advantages and disadvantages of this technique will be reviewed in the context of the exploration of thick, fixed or living tissue imaging. Tips and tricks will be shared and a focus will be made on fluorescence lifetime imaging (FLIM) to separate auto fluorescence from specific fluorophore.
In parallel, we will cover the theoretical and practical basis in super-resolution microscopy based on the detection of individual molecules using the dSTORM (direct STOchastic Reconstruction Microscopy) method. For this we will go from the preparation of the sample to the quantification of the images acquired in 2D and 3D[/su_tab] [su_tab title=”Lectures”]Lectures associated to the practical session will be given by:

[su_tabs active=”1″ vertical=”yes”][su_tab title=”Organisers”]Audrey Salles, Mickael Lelek[/su_tab] [su_tab title=”Description”]During this module, we will present to the attendees the process to image a biological structure using 3D-STORM and 3D-SIM. Using the same sample, we will show the gain in spatial resolution between using STORM method but also the temporal gain using SIM microscopy.  During the workshop, the trainees will work on a home made system STORM and commercial SIM microscope (Elyra 7 – Lattice SIM from Carl Zeiss). Concerning the STORM experiments, 2D and 3D acquisitions will be acquired. In the 3D acquisitions, the axial positions of the single molecule will be encoded in a non common PSF (Double Helix PSF). ZOLA-3D software will be used to localize single PSFs and to visualize the 3D high resolution image of the imaged samples. Some important notions seen during the lecture will be introduced in order to get the best high resolution image.  Concerning the SIM experiments, the same biological structure will be used. For this modality, a detailed explanation of the advantages and disadvantages of structured illumination will be given as well as a focus on time resolution and live sample imaging. Part of the session will be devoted to the artefacts that can be generated in super-resolution imaging followed by a discussion of the methods and tools for diagnosing them. Then the trainees will appreciate the gain in resolution between the both systems.[/su_tab] [su_tab title=”Lectures”]Lectures associated to the practical session will be given by:
