How to Keep Your Samples Under Physiological Conditions

The Coral Life workflow combines dynamic data with the best possible sample fixation by high pressure freezing. However, good sample preservation won’t help if your cells are stressed by temperature…

Putting Dynamic Live Cell Data into the Ultrastructural Context

With workflow Coral Life, searching for a needle in the haystack is a thing of the past. Take advantage of correlative light and electron microscopy to identify directly the right cell at the right…

Fast, High-quality Vitrification with the EM ICE High Pressure Freezer

The EM ICE High Pressure Freezer was developed with a unique freezing principle and uses only a single pressurization and cooling liquid: liquified nitrogen (LN2). This design enables three major…

Investigating Synapses in Brain Slices with Enhanced Functional Electron Microscopy

A fundamental question of neuroscience is: what is the relationship between structural and functional properties of synapses? Over the last few decades, electrophysiology has shed light on synaptic…
