Virally labeled neurons (red) and astrocytes (green) in a cortical spheroid derived from human induced pluripotent stem cells. THUNDER Model Organism Imager with a 2x, 0.15 NA objective at 3.4x zoom was used to produce this 425 µm Z-stack (26 positions) which is presented here as an Extended Depth of Field (EDoF) projection.

Guide to Live-Cell Imaging

For a wide range of applications in various research fields of life science, live-cell imaging is an indispensable tool for visualizing cells in a state as close to in vivo, i.e. living and active, as…
Image of roundworm C. elegans acquired with a M205 FA fluorescence automated stereo microscope in combination with Rottermann contrast. Areas labelled with mCherry are seen as reddish purple.

A Guide to C. elegans Research – Working with Nematodes

Efficient microscopy techniques for C. elegans research are outlined in this guide. As a widely used model organism with about 70% gene homology to humans, the nematode Caenorhabditis elegans (also…
A fruit fly (Drosophila melanogaster) observed with an Ivesta 3 stereo microscope during fly pushing (sorting of the flies). The scale bar length is 1 mm. Image courtesy of M. Benton, EMBL, Heidelberg, Germany.

A Guide to Using Microscopy for Drosophila (Fruit Fly) Research

The fruit fly, typically Drosophila melanogaster, has been used as a model organism for over a century. One reason is that many disease-related genes are shared between Drosophila and humans. It is…

A Guide to Zebrafish Research

To obtain optimal results while doing zebrafish research, especially during screening, sorting, handling, and imaging, seeing the fine details and structures is important. They help researchers make…
