Clearing tissue is now a powerful and accessible technique for studying thicker samples in greater detail. The recent proliferation in tissue-clearing reagents and methods has made the technique more effective and more reliable over a greater range of samples from tissues to organs to whole animals. Once a suitable tissue-clearing regime has been established for a sample the following consideration is what image acquisition modality to use? Two potential options are a spinning disk confocal and a lightsheet microscope, both of which we will present in this workshop. Some of the parameters of a sample or the feature of interest will clearly direct this decision; for example, imaging a whole cleared mouse would typically preclude a spinning disk confocal and imaging a cleared tissue sample at super-resolution would typically preclude lightsheet microscopes. When imaging cleared specimens multiple factors need to be taken into consideration, foremost is a careful evaluation of the volumetric data such that it meets resolution requirements and is an accurate 3D representation of the sample. Other considerations are practical including: safety and ease of sample handling, ease of capture and duration of data acquisition. In this workshop we present our Marianas SDC inverted microscope system featuring a CSU-W SoRa super-resolution spinning disk confocal and our Cleared Tissue LightSheet (CTLS) microscope system and explore cleared tissue samples that could be imaged by each modality and compare the benefits and limitations of each technique.

SMLM cell imaging with Massive Photonics DNA-PAINT kits, demonstrated on Abbelight’s SAFe360
Biological imaging has successfully pierced the nanoscale in recent years; resolving the intricate interaction of multiple targets in a system naturally represents the next step in the evolution of fluorescence nanoscopy. For Single molecule localization microscopy (SMLM) , one of the most promising ideashas been to spectrally demix the fluorescence emission of several dyes with similar spectral properties, mostly applied toStochastic optical reconstruction microscopy (STORM). Meanwhile,DNA-PAINT (DNA-Point accumulation for imaging in nanoscale topography) inherentlyholds great potential for multicolor imaging due to its different approach to attaining the “blinking” required for SMLM. DNA-PAINT relies on the rapid hybridization and dehybridization of short complementary DNA strands, retaining a dye long enough close to the target to collect a few thousand photons and “localize it” before the dye diffuses off again. DNA-PAINT imagers (dye coupled to the DNA strand) are independent of the secondary antibody which enables imaging with reduced photobleaching, flexible adjusting of the imager’s concentration or replacing it with another imager With the specificity of the DNA imager strands, nearly limitless multiplexing of different targets with just a few laser sources is possible. Massive Photonics provides DNA-PAINT staining kits consisting of secondary antibodies or single-domain antibodies and complementary imagers, easy to integrate into a regular immuno-labeling routine.
With this workshop, we would like to demonstrate the versatility in multiplexing that the combination of Massive Photonics staining kits with the Abbelight SAFe360 setup yields: From consecutive imaging of multiple targets, over simultaneous two-color imaging to spectral demixing. We will show the imaging procedure of an exemplary one and/or two-color imaging on Cos7 cells or cultured hippocampal rat neurons

The ACQUIFER Imaging Machine – Workflows for Automated Imaging, Photomanipulation and High Content Screening
Phenotypic screening of complex cellular or whole organism model systems is increasingly employed in biomedical and pharmaceutical research. To fully exploit their potential, novel imaging workflows and tailored tools compatible with the automated imaging and spatiotemporal scoring of cell- and tissue-specific phenotypes are needed.
The ACQUIFER Imaging Machine (IM) is a versatile and flexible automated wide-field fluorescence microscope for high-content imaging of 2D/3D cell-cultures, fixed tissues sections and small model-organisms. The system features a unique moving optical unit in combination with a static sample holder, rendering it ideal for non-adherent and motion-sensitive specimen. For optimal time-lapse in-vivo imaging, the sample chamber is equipped with a Peltier device for highly precise temperature control.
In this workshop, we will demonstrate the unique hardware design and exemplify automated imaging applications. We will illustrate our workflow concept for automated imaging, feedback microscopy and High-Content-Screening using the ACQUIFER IM and associated software tools. Furthermore, we will discuss the optional laser-module that allows scaling-up of challenging photomanipulation experiments, such as photodamaging or photoconversion.
The IM control software ensures simple and intuitive configuration of standard imaging protocols. Complex acquisition procedures can be customized thanks to built-in scripting support (C#-based) or via dedicated extensions for external applications (Fiji, Python etc). The powerful imaging capabilities of the IM are complemented by the ACQUIFER PlateViewer, an easy-to-use software for browsing and visualization of large high-content screening datasets, and an interface for supervised feedback microscopy. The PlateViewer includes a plugin mechanism, allowing interfacing with external software for custom image-analysis. The open interface enables remote-control of the system by external software or integration in a robotic setup. It also allows feedback microscopy workflows for pre-scan/re-scan applications, such as automated centring applications, using Fiji and the PlateViewer.

Obtain and manage quality control data on your microscopes
One of the core facilities’ duties is to provide end-users, usually researchers in life sciences, a fleet of microscopes at a level of performance compatible with their experiments. This is not an easy task because the performance of such devices tends to fluctuate or deteriorate over time for many reasons: misusing, aging, environment fluctuations, etc. This is especially true for high end imaging systems such as confocal or super resolution microscopes. Having access to a unique, reliable, and easy-to-use device to ensure microscopes’ performance would certainly make easier this tedious task.
To get quantitative and reproducible data, assessing the performances of fluorescence microscopes is a prerequisite before any imaging campaign. For example, system co-registration accuracy should be evaluated before any co-localization study; System field uniformity and intensity response before any study where intensity in the image matters; Spatial resolution before any study aiming at counting objects close to each other, etc.
Three years after our last presence at ELMI, we are happy to come back and present during this workshop the novelties we have developed in the meantime: improved hardware products, new analyses from 3D patterns, new analyses related to non-Argolight products, improvements in user interface and user experience, etc. Above all, the presentation aims to show how the quality control of fluorescence microscopes can be standardized with Argolight software solutions, and how the generated quality control data can be managed and centralized for later reporting.

Measuring Random Motility and Wound Healing with Livecyte: are you only scratching the surface?
Dreading another day of monotonous mouse clicking to manually track cells? What if your derived motility measurements are not as reliable as you think? Livecyte can automatically track thousands of cells presenting clear advantages in the accuracy of motility metrics, as well as saving a considerable amount of time and energy.
In this workshop we will explore some of the sources of error when manually tracking live cells, in particular the variability from user to user and the lack of consistency and accuracy in clicking on the centre of a cell. These errors lead to discrepancies in derived cell track lengths. We reveal how Livecyte overcomes these limitations with its standardised automated tracking algorithm shown to alleviate the high level of variation between users manually tracking the same cells. In addition, by accurately tracking and analysing individual cells, Livecyte can give a greater depth of information such as speed and directionality. All these metrics and data are conveniently organised into Livecyte’s Motility and Wound Healing Dashboards which make it easy for users to understand the motility behaviour of their cells.

Exploring the World of Multiplexing Immunofluorescence in Human Immune System Studies
Distinguished Guest Speaker Thomas Diefenbach, The Ragon Institute Boston
In fields such as immunology, where methods such as flow cytometry typically employ 15 to 30 markers per cell, the necessity for characterizing cell populations similarly in tissue is limited by the number of markers one can interrogate using conventional epifluorescence or confocal microscopy approaches. In this virtual workshop, various approaches for multiplexing fluorescent markers in tissue will be combined with the TissueFAXS high-throughput automated slide scanning systems by TissueGnostics to demonstrate the ease with which one may examine far more than the standard four or five fluorophores at the single cell level. Potential applications for such approaches will also be outlined that examine cell-to-cell interactions and dynamics in tissues in a highly regional and quantitative manner utilizing analysis tools afforded by the TissueQuest and StrataQuest analysis software packages.

Every Molecule Counts - the ONI super-resolution platform just got even better
Studying spatial protein organization or protein copy number, clustering and mobility at the molecular level is extremely important from both a diagnostic and treatment perspective. Looking at cellular structures beyond the diffraction limit with a resolution of 15-20 nm with robust quantification has been enabled with Single-molecule localization microscopy (SMLM) like STORM or PALM. ONI has created the world’s first desktop super-resolution microscope, the Nanoimager, which is designed to operate on a standard lab bench and has a footprint smaller than a piece of A4 paper, with the most intuitive and simple software interface, making it also accessible to researchers not specialized in high end microscopy techniques with one major goal: make it accessible and simple to use.
It is really important to enable users to extract quantitative information from their localization-based images. We have done this by designing a cloud-based analysis software called CODI (COllaborative DIscovery). CODI helps users analyze their single-molecule data by extracting quantitative information on protein clustering, cluster size and area, cluster density, and so much more. It enables all researchers to upload their data, share or collaborate with other scientists, whilst gaining meaningful insights about their data.
During this workshop we will perform a two-color STORM on mitochondrial samples (TOM20 and HSP60) and reveal the sub-mitochondrial compartmental organization with 20 nm resolution. The aim is to introduce SMLM imaging as a powerful tool for rapid and multiplexed characterization of cellular structures along with a visual and quantification analysis platform CODI developed by us. We will follow up the workshop with an open discussion on the wide-ranging applicability of the Nanoimager in different biological applications encompassing the field of immunology, neurobiology, cell biology and cancer.
