Super Resolution – Confocal Correlative Imaging |
Super Resolution imaging using single molecule localization techniques (PALM, STORM) provides the highest resolution available for a fluorescence microscopy modality. While super resolution provides an opportunity to examine the relationship of proteins and structures down to 20 nm, interpreting the data within a larger context can sometimes be difficult.
Acquiring confocal images as references along with super resolution images provides context for visual interpretation as well as providing a guide for analysis of super resolution data. The Vutara 352 with Opterra SR option provides a platform for correlative super resolution confocal imaging. The Opterra SR high speed confocal can be used for sample navigation as well as acquiring references images, which can be merged to allow interpretation and guided analysis of super resolution data.

Light as the Independent Variable: Photomanipulation Techniques for Confocal and Multiphoton Microscop |
A variety of techniques are available to biological microscopists that allow them to use light as a stimulus to produce measurable changes in their sample of interest. These techniques include uncaging, fluorescence recovery after photobleaching (FRAP), photoactivation, photoconversion and photoablation.
We will cover the basic principles of these various techniques and examine their value in various experimental protocols. We’ll show examples of the various techniques using data collected on Bruker Ultima multiphoton microscopes and Opterra multipoint scanning confocal microscopes.

Quantitative Super-Resolution Applications in Life Science Using Single Molecule Localization Microscopy |
In this webinar we will discuss examples of how researchers have used this quantification capability of SML to address key biological questions. The Vutara 350 super-resolution microscope has thus been engineered to enable researchers to fully harness the power of quantitative SML imaging by offering, three-dimensional, multi-color, live cell imaging capability coupled with custom-designed Vutara SRX software.

Exploring in vivo Neural Circuit Activity with Simultaneous All Optical Manipulation and Recording |
with guest speaker Dr. Adam Packer
Dr. Packer will review his recent work in which he utilized a Spatial Light Modulator (SLM) interfaced to a multiphoton microscopy system in order to simultaneously use optical stimulation and optical recording to study neural networks. A major benefit of the use of the SLM is that tens of neurons can be simultaneously stimulated, while at the same time imaging neuronal activity in a field using a calcium indicator.

Live Cell Super-Resolution Imaging |
In this webinar we will cover the technology and sample preparation optimization techniques necessary for successful live single cell molecule localization (SML) super-resolution imaging. Speed of imaging and data processing, laser intensity, and availability of live cell compatible fluorescent labels are all key factors that need to be considered when designing a live cell super-resolution experiment. The Bruker Vutara 350 super-resolution microscope has been engineered to be live cell ready; the sCMOS camera enables video-rate imaging, parallel processing computer architecture and multi-emitter fitting enable real time localization, and high laser powers enable rapid photoswitching of fluorophores. Combining Vutara 350 live cell ready technology with the rapidly evolving field of fluorophore engineering for live cell applications promises to overcome the limitations faced thus far in live cell super-resolution imaging.

Super-resolution Microscopy and Its Applications in Fast and Complex Biological Systems |
Super-resolution microscopy has revolutionized the field of biological imaging by providing new insights into biological processes in fields as diverse as developmental biology, neuroscience, cardiovascular research, genetics, infectious disease, and DNA/chromatin structure. The Vutara 350 super-resolution microscope offers a ten-fold improvement in resolution in comparison to traditional light microscopy techniques and is capable of achieving resolutions of 20 nm laterally and 50 nm axially. The Vutara 350 is based on a patented 3D biplane single molecule localization platform.
In this webinar we discuss the basic principles of operation and features of the Vutara 350 super-resolution microscope. The capability to do 3D multicolor imaging, high speed live cell imaging, 3D particle tracking, and z-stacking in various biological systems such as cells, tissue, drosophila, C. elegans, bacteria and virus makes the Vutara 350 very versatile.

A Deeper Understanding of In Vivo Immune Cell Function Through the Use of Multiphoton Intravital Microscopy |
Multiphoton Intravital Microscopy (MP-IVM) is an advanced imaging technique that allows visualization of fluorescently labelled cells in their natural environment, allowing imaging at depths of hundreds of microns into intact organs in vivo.
MP-IVM has proven to be a revolutionary tool in the study of immune cell function, allowing observation of the functions in lymphnoid as well as non-lymphoid tissues, such as sites of infection or tumors. In addition to qualitative observation of immune cell behavior, MP-IVM lends itself to quantitative measurements of cell migration, cell-cell interactions and the activity of signaling pathways.

The Unique Scanning Mechanism Design of the Opterra Multipoint Scanning Confocal Microscope |
This webinar will discuss the unique scanning mechanism design of the Opterra™ Multipoint Scanning Confocal Microscope, which lends itself to acquisition of spectral data sets at speeds appropriate for imaging of live cells and small organisms. Opterra's 1-D array of 32 pinholes, coupled with an Amici prism, allows collection of full spectral data sets of 15 channels at speeds up to 4 spectral data sets per second. Spectral data sets can be acquired with time lapse, Z series and stage control, thus allowing a full range of multidimensional data acquisition methods, including time-based volumetric imaging, 3-D stage montages and timed-based acquisition from multiple stage locations.
