Elucidate the underlying mechanisms of Parkinson's disease

Parkinson’s disease (PD) is a debilitating, chronic, and progressive neurological disease that affects around 10 million people worldwide. PD is accompanied by loss of motor function and, without a curative treatment, care remains palliative. Early diagnosis of PD and similar neurodegenerative diseases is difficult because of their common symptoms and pathophysiology and the lack of understanding of their distinguishing molecular characteristics. Thermo Fisher Scientific is committed to developing research tools for neuroscientists investigating the molecular mechanisms of PD and other neurodegenerative diseases using in vitro, ex vivo, and in vivo experimental systems.

About the cover

Immunofluorescence analysis of ZO-1 (red) and SOX2 (gray) in human iPSC–derived forebrain organoids. At day 40, organoids were fixed with 4% formaldehyde for 1 hr at room temperature and incubated in a 30% sucrose solution overnight at 4°C. The organoids were then embedded, cryosectioned at 5 μm, permeabilized with 0.2% Triton X-100 for 20 min, and blocked with 10% donkey serum in PBS for 30 min at room temperature. Organoid slices were incubated with a 1:500 dilution of Invitrogen ZO-1 mouse monoclonal antibody (clone ZO1-1A12) and Invitrogen SOX2 rabbit polyclonal antibody, and a 1:1,000 dilution of a MAP2 chicken polyclonal antibody in blocking buffer overnight at 4°C. Samples were then stained with a 1:1,000 dilution of Invitrogen Alexa Fluor 568 donkey anti–mouse IgG (red), Invitrogen Alexa Fluor 647 donkey anti–rabbit IgG (gray), and Alexa Fluor 488 donkey anti–chicken IgG (green) secondary antibodies, as well as DAPI (blue), in blocking solution at room temperature for 1 hr. Images were taken on a Nikon Inverted Eclipse Ti-E Microscope at 20x magnification. Scale bar: 50 μm. Used with permission from Zhexing Wen, Emory University School of Medicine, Atlanta, Georgia.

Spheroid cell culture: Practical solutions for frequently asked questions

3D cell models—including spheroids, tumor spheroids or tumoroids, and organoids—have become important experimental tools for cancer biology and immunology, as well as for drug screening, discovery, and development. 3D models are relevant for many different application areas because their microenvironment can resemble the microanatomy of in vivo systems better than traditional 2D models. The formation and growth of these 3D cell models, however, can be more difficult because of the increased complexity that comes with spheroid culture.

Spheroid size and uniformity across culture wells and plates and the expression of subcellular molecular markers are key concerns that can be addressed with the appropriate cultureware, media, fluorescent reagents and assays, and instrumentation. Thermo Fisher Scientific offers Invitrogen, Gibco, and Thermo Scientific products across the entire 3D workflow, in addition to resources, tip and tricks, and support for frequently asked questions.

Watch the on-demand webinar "Best practices: 5 steps to live-cell imaging"

Fluorescence imaging of live cells is a powerful approach for the study of dynamic cellular processes and events. Recent advances in fluorescent dye development and imaging technology have led to the application of live-cell imaging in diverse fields, including developmental and stem cell biology, drug discovery, and environmental studies.

The webinar "5 steps to live-cell imaging" from Thermo Fisher Scientific summarizes what we have learned from over 40 years of cell imaging research and expertise. Designed for those new to live-cell imaging as well as experienced researchers, this webinar demonstrates how to obtain publication-quality live-cell images routinely and efficiently, while minimizing waste and avoiding costly mistakes. We also discuss long-proven tools and protocols for achieving the best possible results in your live-cell imaging workflow.

Behind the Bench blog: What’s new with antibodies

We are continually updating our Invitrogen antibody portfolio with verified primary antibodies for use in flow cytometry, IF/ICC/IHC, western blotting, and ELISAs. See what’s new in two blog posts:

  • Let’s get ‘specific’ about the TNFR pathway!” focuses on the TNFR pathway and recommends CRISPR-validated Invitrogen antibodies for key proteins in this pathway
  • DIY neurons for antibody validation” describes our use of stem cells to generate several different types of neuron progenitor cells, which can then be employed for antibody validation*

5th Annual Thermo Scientific Tandem Mass Tag (TMT) Research Awards: Winners announced!

Isobaric chemical tags are powerful tools that enable multiplexed identification and quantitation of thousands of proteins from different samples, using tandem mass spectrometry (MS/MS). Tandem mass tag (TMT) labeling reagents contain up to 11 different isobaric compounds for labeling protein samples in parallel and then combining them for analysis on high-resolution MS/MS platforms such as the Thermo Scientific Orbitrap Fusion Lumos series, Orbitrap Elite device, and Q Exactive series, each supported by Proteome Discoverer 2.2 Software.

We are pleased to announce this year’s recipients of the Thermo Scientific TMT Research Awards, given annually to three researchers selected by a panel of judges from Thermo Fisher Scientific and Proteome Sciences in recognition of the innovation and potential impact of their use of TMT labeling reagents in conjunction with other Thermo Scientific MS reagents. These recipients were recognized at the 2019 American Society for Mass Spectrometry (ASMS) annual meeting:

  • Gold Award—Dr. Amirata Saei Dibavar, Karolinska Institute, Sweden
  • Silver Award—Dr. Anja Andrejeva, Cambridge Centre for Proteomics, University of Cambridge, UK
  • Bronze Award—Dr. Paula Díez, Leiden University Medical Center, The Netherlands
