Capturing Developmental Dynamics in 3D

This application note showcases how the Viventis Deep dual-view light sheet microscope was successfully used by researchers for exploring high-resolution, long-term imaging of 3D multicellular models…

These images illustrate the need for multiple z-slices to capture all gH2Ax foci in a given cell and get an accurate count.

Development and Derisking of CRISPR Therapies for Rare Diseases

This on-demand presentation by Dr. Fyodor Urnov and Dr. Sadik Kassim, originally delivered at ASGCT 2025, focused on a critical challenge in genetic medicine: how to scale CRISPR therapies from…

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…

The “Waffle Method”: High-Pressure Freeze Complex Samples

This article describes the advantages of a special high pressure freezing method, the so-called “Waffle Method”. Learn how the “Waffle Method” uses EM grids as spacers for high-pressure freezing,…

Mastering Polymer Sectioning with Helmut Gnaegi

When it comes to ultramicrotomy, few names carry the weight of Helmut Gnaegi. As co-founder of Diatome, a global leader in diamond knife technology, Helmut has spent decades refining the art and…
