Complex lipid compositions of a variety of samples, like tissues, cells, cellular preparations, organelles, body fluids and others are challenging to analyze quantitatively in a single, straightforward measurement.

Here we present a fully quantitative lipidomics technology characterized by high precision not only on different days but also in different laboratories. At the same time our technology allows for high lipid coverage, without compromising the throughput.

To scrutinize the feasibility of our approach we applied it to human blood plasma, where it proved:

  1. to be comprehensive, covering 22 different lipid classes encompassing more than 200 lipid species;
  2. to be high-throughput amenable, allowing for the analysis of hundreds samples per day;
  3. to achieve absolute quantification of individual lipid molecules, by inclusion of lipid class-specific internal standards

Tools to analyze single cells for their discrete characteristics are becoming increasingly mainstream, bringing with it significant scientific momentum. Scientists understand that cell populations are heterogeneous and bulk measurements can mask events when using the law of averages. However, current genomics approaches introduce variables that can result in over/under representation of certain cell types. Ultra-sensitive fluorescent in situ hybridization (FISH) that relies on signal amplification rather than transcript amplification provides an outstanding single-cell validation tool. These techniques illustrate subcellular, population dynamics/cell frequencies, or indicate morphological context. ViewRNA® and PrimeFlow® FISH platforms for microscopy and flow cytometry incorporate a proprietary probe design using branched DNA (bDNA) signal amplification technologies that result in excellent specificity, low background, and high signal-to-noise ratios.

Presenter: Dr. Kamala Tyagarajan, Ph.D

Understanding the linkages between cell cycle and cell death pathways has become increasingly important to elucidating the action of toxins and anti-cancer compounds, as well as the fundamental mechanisms of cell division. Cell biology research therefore requires simple, accessible tools to determine impacts on both cell cycle and cell health in order to characterize the pathways by which cells are affected by treatments or conditions. We will present simplified flow cytometric methods using the Muse© Cell Analyzer to study cell cycle distribution together with data from well-known apoptosis and cell death assays. You will learn how the parallel study of cell cycle and cell stress/death can provide enriched information on the impact of treatments, and provide a comprehensive picture of cellular status and health.

Presenter: Bob McCarthy

Crude collagenase is commonly used to recover cells from tissue. The benefit of using this low cost product comes at a price: the inability to define the biochemical components responsible for the success of cell recovery. As life science research transitions toward translational medicine, these reagents should be better defined. This tech talk provides an overview of how collagenase enzymes are manufactured, the limitations of using crude enzymes in cell isolation procedures, and the advantages of using a new defined, enriched collagenase product (DE Collagenase) that contains primarily collagenase and a purified protease. Comparison of the biochemical characteristics of crude and DE Collagenase enzymes will show how definition of key enzymes responsible for cell isolation minimizes the need to prequalify lots prior to purchase.

Presenter: Teng-Leong Chew, PhD Director, Advanced Imaging Center Howard Hughes Medical Institute Janelia Research Campus

Learn about two new detection and acquisition strategies for the ZEISS Airyscan detection module for laser scanning microscopy. ZEISS Airyscan, a new detector concept designed for improved laser scanning confocal microscopy, enables the simultaneous increase of both resolution and signal-to-noise ratio over traditional confocal imaging. Both modes – sensitivity and two-photon – extend the Airyscan benefits of resolution and signal-to-noise ratio to address more sample types.

Presenter: Dr. Xufeng Wu, NHLBI NIH

Confocal microcopy is and has been a mainstay of light microcopy for decades given the flexibility of a commercially available system. However, the resolution of a confocal microscope is still diffraction limited with a lateral resolution of ~250nm. With the recent advent of superresolution techniques (PALM, STORM, STED, and SIM), new commercially available systems are being used to image beyond the diffraction limit. As a result, the increased spatial resolution novel information regarding cell structure and function can be obtained. Recently the new Zeiss Airyscan detector was introduced as another method of superresolution and represents a good blend of resolution, sensitivity and speed. In this session, Dr.Xufeng Wu will present her recent experiences using the Airyscan for imaging cyoskeletal dynamics, organelle, membrane trafficking, and three-dimensional.

Presenter: Manasa Gudheti, Ph.D.

Super-resolution microscopy has made a significant impact in the field of biological imaging. Most imaging has been targeted at fixed specimens with a few live-cell applications. The Vutara 352 super-resolution microscope has been engineered for live-cell applications through the optimization of spatial and temporal resolution in single-molecule localization imaging. Its sCMOS detector enables video rate imaging along with two color simultaneous imaging in live cell and 3D particle tracking experiments. The biplane based detection path enables imaging thicker samples such as whole mount Drosophila and offers deeper penetration into tissues.

The Vutara 352 also includes real time localization along with several statistical and live cell analysis features for processing data. In summary, the Vutara 352 microscope is a powerful super-resolution imaging and analysis tool.

Presenter: Melike Lakadamyall, Ph.D.

Super-resolution microscopy has emerged as a powerful tool to image cells at the nanoscale, giving important insights into biological processes at the molecular level. The revolutionizing impact of these methods has recently been recognized by the Nobel Prize/Chemistry. While exciting developments have significantly advanced the capabilities of super-resolution microscopy, important challenges remain in pursuing its applications in biology. One limitation is the compromise between spatial and temporal resolution that make these methods poorly suited to study dynamic processes. Another challenge is our limited capability to extract quantitative information from the super-resolution images, which is confounded by the photophysics of the fluorophores. I will show how we are developing new approaches to overcome these challenges and demonstrate novel biological applications of super-resolution.

Presenter: Luciano Lucas

Low-toxicity imaging technologies have enabled an expanding group of researchers to examine cellular processes over long periods and at sub-cellular resolution. Developmental, stem cell and cancer cell biology have all benefited greatly by employing techniques such as spinning disk confocal, light sheet and structured illumination microscopy. A major bottleneck felt by scientists is the efficient visualization and analysis of long 3D time-lapses. Building on the powerful file handling of Imaris and functionality of ImarisTrack and ImarisCell we are introducing a new tool set which enables researches to study cell division, track and interactively explore cell lineages. This talk will be the launch of Imaris 8.2. I8.2 tackles the bottleneck mentioned above thus enabling the scientific community to post and test previously impossible to test hypothesis.

The emergence of the CRISPR-Cas9 system to generate alterations in the mammalian genome has expanded the scope of functional biology and many parallels have been drawn between the CRISPR-Cas9 system and the RNAi pathway. While fundamentally different, the challenges of off-targeting and poor functionality can be inherent to both systems and cause concerns about data interpretation and reliability. Used together, these technologies can provide a robust insight into the functions of genes in mammalian cells. In this talk we will describe a novel approach to understanding the requirements of both function and specificity of crRNAs and present data supporting the development of the next generation of shRNA constructs.

If a picture is worth a thousand words, then a movie should be worth tens of thousands of data points. The timely integration of affordable time-lapse live-cell microscopy provided by Etaluma, along with genetically encoded biosensors and quantitative image analysis approaches, have enabled our laboratory to develop a robust and extremely low cost screen.

Our genetically encoded biosensor harnesses cell-cycle-dependent transcriptional and post-transcriptional regulation of fluorescent reporter proteins that ultimately enable multi-parameter quantification of each of the main phases of the cell cycle (i.e. G0, G1, S, G2/M) at single cell resolution in living cells and tissue. This economical system is being applied to novel drug and gene discovery in regenerative medicine and cancer.

Presenter: Leanna Ferrand, Product Support Leader

Live cell imaging has long been one of the most challenging yet most rewarding applications in fluorescence microscopy.  Recently, super resolution microscopy has allowed researchers to investigate previously unresolvable structural details in their samples. Combining these techniques to perform live cell super-resolution imaging creates additional challenges, but greatly increases the potential scientific reward. Advances in Structured Illumination Microscopy (SIM) have made biologically relevant live cell SIM a reality. SIM offers researchers a two-fold increase in resolution both laterally and axially, revealing those structural details previously unresolved with conventional microscopy. SIM requires the least amount of input light, thus reducing photobleaching and phototoxicity. SIM is compatible with standard fluorophores and sample preparation techniques, requiring minimal sample optimization and is becoming the most approachable live cell super resolution method.

Presenter: Steve Offer

Steve Offer, Assistant Professor of Pharmacology at the Mayo Clinic School of Medicine, describes the cellular metastasis models his lab has developed to better understand the molecular changes that occur during colorectal cancer metastasis. Steve will discuss the correlation between changes in the epigenetic landscape, microRNA expression, and gene expression, and how these changes affect tumor progression. Along with traditional approaches to study metastasis, Steve’s lab has leveraged the throughput and sensitivity of the xCELLigence real-time cell analyzer and the NovoCyte flow cytometer to test specific parameters of candidate metastasis-associated signatures identified by his lab. These results are expected to help identify early-stage indicators of later tumor aggressiveness and to facilitate the development of therapeutics designed to specifically target cancers based on discrete molecular profiles.

Presenter: Paul Diehl PhD.

The CRISPR/Cas9 system is a targeted gene-editing tool adapted from Streptococcus pygogenes and can be used to permanently knock out target genes. It has revolutionized the genomics research along with the earlier tool of RNAi. Genome-wide loss-of-function pooled screens provide a direct approach to identify genes regulating biological responses and find new therapeutic targets. While RNAi screens have proven effective, CRISPR/Cas9 provides an alternative screening approach. To complement our shRNA screening platform, we developed pooled sgRNA libraries for functional CRISPR knockout screens and compared results from sgRNA and shRNA library screens of PDX-derived cell lines. This talk will provide an overview of the functional genomics screening approaches and focus on comparison of the two available methods.

We describe how to perform high resolution multi protein micro-patterning using Light Induced Molecular Adsorption (LIMA). LIMA is based on a photo-initiator able to reverse the antifouling property of polymer brushes when exposed to UV light.

The density of adsorbed molecules scales linearly with the dose of UV and the low background allows for the sequential printing of multiple proteins. Our optical set-up (widefield DMD based projection system + epifluorescence microscope) allows us to generate patterns ranging from 500nm to 1 mm and controlled gradients of arbitrary shape. The range of application extends from the single molecule up to the multicellular scale with an exquisite control over protein density.

Altogether, LIMA allows for fast high resolution patterning of multiple proteins with applications to biomedical research.

G protein coupled receptors produce a myriad of effects through a variety of effectors. To study these effects, we created genetically-encoded fluorescent biosensors for cAMP and DAG. These sensors are analogous to the GCaMP and GECO Ca2+ sensors, in that the analyte binding domains are fused to a single fluorescent protein. A major advantage of single fluorescent protein sensors is that they can be combined for simultaneous measurement of multiple analytes. These sensors are robust enough for detection with epifluoresence microscopy or fluorescence plate readers. The sensors are packaged in viruses for delivery to mammalian cells. Changes in fluorescence are reproducible from cell to cell. cADDIs, a cAMP sensor detects both Gs and Gi-coupled responses. Upward and Downward DAG sensors detect Gq signaling.

Microscopy images suffer from artifacts like blurring, noise, and chromatic aberration which all distort your image and affect the ‘true’ object distribution. Fortunately, the most important distortion factor of a fluorescence microscope – blurring – can be captured as the Point Spread Function (PSF). Huygens uses this PSF to restore the original constituent object. As a result, image contrast and resolution are significantly improved, and noise decreased. Additional chromatic aberration, crosstalk, and unwanted movement can also be measured and corrected with Huygens. We will present Huygens as a complete package for the restoration, rendering, and analysis of images from a range of microscope types (widefield, confocal, spinning-disk, multi-photon, STED 3D). The latest advances in Huygens GPU-accelerated deconvolution and SPIM/Light Sheet image restoration will also be highlighted.

Many of the antibodies published in biomedical research suffer from the lack of properly controlled studies into their reliability and reproducibility against specific antigens. Issues with improperly characterized antibodies prevented the replication of data in 47 of 53 preclinical studies. It is estimated that the resulting waste in labor and consumable costs are $350 million annually just for US researchers. In order to address this crisis two complimentary technologies have been developed that will create a more structured, accurate antibody system of validation. Bio-Layer Interferometry will be shown to determine Ab concentration, structural integrity, relative KD measurements, and epitope binning. Size exclusion chromatography multi-analyte platform will be shown to determine Ab off-site binding, specific binding, binding to protein complexes, and monomeric forms of proteins.

Presenter: Melanie Styers

The extracellular vesicle (EV) research field has dramatically increased in the last five years. Using a high-speed flow cytometric sorter, EVs may be isolated at high rates such that researchers can differentially separate, isolate and characterize the EVs for downstream analysis. EVs contaminated with proteins, dye or antibody aggregates of the same size, but different mass, can be characterized based on these physical properties in the analytical ultra-centrifuge. We demonstrate that the XLA/I Analytical Ultracentrifuge (AUC) effectively separated particles on their sedimentation velocity and clarified issues with dye aggregation vs EV staining. Additionally, the DelsaMax Particle Characterizer allowed for quick analysis of post-sorted populations. The Astrios EQ Cell Sorter was able to sort EVs and AUC provided additional analysis for exosome purity.

Presenter: Colin Coates

Cancer immunotherapy offers the potential for eradication of tumor cells and the prevention of cancer recurrence. In this study, we describe live cell imaging assays designed to quantify T cell killing of tumor cells in co-culture. PBMCs or isolated CD8+ T cells were added to tumor cells in combination with activators and a non-perturbing caspase-3/7 reagent in 96 or 384-well plates. Phase and 2-color images were captured using IncuCyte ZOOM™. Tumor cells and apoptotic cells were quantified using image analysis. These data demonstrate that a live cell imaging approach can discern the full time course and specificity of T cell killing, without lifting cells, using Ab labels or radioisotopes. HD images and time-lapse movies facilitate a clear understanding and compelling verification of the underlying biology.
