Blood vessel system of a zebrafish larvae

Overcoming Challenges with Microscopy when Imaging Moving Zebrafish Larvae

Zebrafish is a valuable model organism with many beneficial traits. However, imaging a full organism poses challenges as it is not stationary. Here, this case study shows how zebrafish larvae can be…

How to Achieve Brain Tissue Resection with GLOW400 AR

Intraoperative MRI is one form of real-time intraoperative visualization, but if more in-depth visualization to identify a tumor during surgery is wanted, intraoperative fluorescence diagnostics is…

How to Automatically Obtain Fluorescent Cells of Interest in a Block-face

Block-face created by automatic trimming under fluorescence. Mammalian cells of interest, stained with CellTrackerTM Green are visualized within the block-face using the UC Enuity equipped with the…

Automated Laser Microdissection for Proteome Analysis

Deep Visual Proteomics Provides Precise Spatial Proteomic Information

Despite the availability of imaging methods and mass spectroscopy for spatial proteomics, a key challenge that remains is correlating images with single-cell resolution to protein-abundance…

These images show the microstructure of a hard metal with 10% cobalt which is used for heavy-duty tools. The large increase in magnification of the right image (compared to the left) has a risk of being outside the useful range or, in other words, empty magnification.

What is Empty Magnification and How can Users Avoid it

The phenomenon of “empty magnification”, which can occur while using an optical, light, or digital microscope, and how it can be avoided is explained in this article. The performance of an optical…

Developing embryos of different species at different stages during the elongation of their posterior body axis, from left to right in developmental time. The labelled regions in red depict a region of undifferentiated cells called the tailbud, with the corresponding region generated from that tissue shaded in grey. Upper row: lamprey; middle row: catshark; bottom row, zebrafish. This figure has been adapted from the following publication: Steventon, B., Duarte, F., Lagadec, R., Mazan, S., Nicolas, J.-F., & Hirsinger, E. (2016). Species tailoured contribution of volumetric growth and tissue convergence to posterior body elongation in vertebrates. Development, 2016. 143(10):1732-41
