Skull Base Neurosurgery: Epidural Lateral Approaches

Surgery of skull base tumors and diseases, such as cavernomas, epidermoid cysts, meningiomas and schwannomas, can be quite complex. During the Leica 2021 Neurovisualization Summit, a unique event…

Two-color caspase assay with tile scan. U2OS cells were treated with the nuclear marker DRAQ5 (magenta) and CellEvent™ (yellow).

Following Multiple Events during Staurosporine Apoptosis

In this video on demand, we show how adding additional markers to an apoptosis kit can markedly increase the amount of information a researcher can obtain from the same experiment. The simultaneous…

New Imaging Tools for Cryo-Light Microscopy

New cryo-light microscopy techniques like LIGHTNING and TauSense fluorescence lifetime-based tools reveal structures for cryo-electron microscopy.

Transverse histological cut of a rabbit tongue. 50 Mpixels images (2326 µm x 1739 µm) in 14 x 18 tiles. Lifetime gives an additional contrast that allows to differentiate different structures in histological stainings.

A Guide to Fluorescence Lifetime Imaging Microscopy (FLIM)

The fluorescence lifetime is a measure of how long a fluorophore remains on average in its excited state before returning to the ground state by emitting a fluorescence photon.

Staining is crucial to revealing details in the specimens.

H&E Staining in Microscopy

If we consider the role of microscopy in pathologists’ daily routines, we often think of the diagnosis. While microscopes indeed play a crucial role at this stage of the pathology lab workflow, they…
