Beginner’s Guide to Performing Optogenetics Experiments on the Ultima 2Pplus, the All-optical Multiphoton Workstation | 25 Minutes

Ewa Zarnowska, Ph.D., Sales Applications Scientist, Bruker

Optogenetics is an ingenious research technique that can help to solve the mystery of the brain’s works. In the process, the neuronal cells are virally transduced to be receptive to the light which is then used for manipulation of brain cells such as to activate them or to inhibit them.

Brain tissue is highly photon scattering where networks of neuronal cells are intricate and span across 3-dimensions. Therefore, observation and optical manipulation of the brain’s cells require advanced technical developments that provide adequate time- and spatial-resolutions.

Bruker’s answer to the needs of modern neuroscience was to design the state-of-the-art all-optical multiphoton workstation, the Ultima 2Pplus, which has which has larger than others field of view and is equipped with...

Fast Imaging of Large Cleared Biological Samples with Light-sheet Microscopy | 30 Minutes

Jürgen Mayer, Ph.D., Senior Application Specialist and Product Manager, Luxendo

Imaging volumetric biological tissue with cellular or sub-cellular resolution has become a key factor in neuroscientific research. Light-sheet microscopy is the state-of-the-art methodology to achieve this, enabling non-destructive data acquisition of intact organs such as an entire mouse brain.

A prerequisite for optical imaging in large (i.e. mesoscopic) samples is tissue clearing. There are numerous different clearing techniques, but all of them have in common that they render biological samples optically transparent. The combination of cleared tissues with light-sheet microscopy is an ideal synergy that allows addressing new questions in neurobiology.

Minimizing sample mounting time, and a fast acquisition followed by a robust processing pipeline is important, especially as...

Super-Resolution Microscopy in Neuroscience | 30 Minutes

Winfried Wiegraebe, Ph.D., Product Manager for Super-Resolution Microscopy, Bruker
Lauren Gagnon, Ph.D., Appliations Scientist, Bruker

Single-Molecule Localization Microscopy (SMLM) was essential in tackling neuroscience questions about the organization of synapsis and the internal structure of neurons. With an optical resolution of 20 nm, SMLM is uniquely qualified to address biological mysteries that require specific labeling as used in fluorescence microscopy but higher resolution than can be achieved with diffraction-limited microscopy.

In addition to applications, we will discuss the basics of super-resolution microscopy and different implementations like dSTORM, PALM, and DNA-PAINT. We will discuss how the unique features of the Bruker Vutara VXL – its workflow-oriented software, biplane detection for improved z-resolution, and fluidics for multiplexed applications – will help you focus on neuroscience and getting superior results.

Precise Spatial Multiplexing for Neuronal Cell Profiling in Mouse Brain Fresh Frozen Tissue with ChipCytometry | 25 Minutes

Adam Northcutt, Ph.D., Senior Scientist, Canopy Biosciences

Understanding the spatial distribution of key neuronal cell populations is critical in advancing our understanding of disease to inform the development of novel therapeutics. Here we present the analysis of fresh frozen (FF) tissue samples from mouse brain using a novel precise spatial multiplexing technology called ChipCytometry, which combines iterative rounds of targeted fluorescent staining with high dynamic range imaging to facilitate quantitative phenotyping with single-cell resolution. Standard FCS files are generated from multichannel OME-TIFF images, enabling identification of cellular phenotypes via flow cytometry-like hierarchical gating. In this study, a 13-plex assay was used to identify and quantify relevant cellular phenotypes and subtypes for neurobiology and neuro-oncology applications. The results show...
