C.elegans, courtesy of Elly van Donselaar, Martin Harterink and Karin Vocking, Utrecht University, Netherlands WHY HIGH PRESSURE FREEZING? High Pressure Freezing arrests aqueous samples in their native state to deliver the best possible sample preservation. Currently cryofixation is the only way to fix cellular constituents without introducing significant structural alterations.

HOLDS THE PROMISE FOR A BRIGHTER FUTURE Symmetric synapse. Dr. Shuwen Chang, Charité Universitätsmedizin, Berlin, Germany “Electron microscopy only captures a static image of a cell. What is the cell doing? What is the true sequence of events in a cellular process? We can make flip books from our micrographs that tell a story, but their arrangement can be influenced by the story we want to tell. With the advent of optogenetic tools a flash of light can trigger dynamic cellular events such as neurotransmission. By coupling a flash of light with rapid high-pressure freezing, regulated vesicle...

Mouse Hippocampal Neurons, Dr. Shigeki Watanabe, Johns Hopkins University WHY HIGH PRESSURE FREEZING WITH ELECTRICAL STIMULATION? Membrane trafficking events at neuronal synapses are the basis of every memory, every emotion. Understanding this highly dynamic event is anything but trivial. The combination of well-established electrophysiology research methods and the technology that allows for millisecond precision in sample preservation is the only tool that may bring the revelation of many unanswered questions such as “How are synaptic vesicles recycled?” Freeze the moment of your discovery

E - Stimulation middle plate check Charge plate Middle plate Assemble the Electrical Stimulation components Program your experiment Load the samples Charge the Middle plate/PSP print Freeze HOW DOES HIGH PRESSURE FREEZING WITH ELECTRICAL STIMULATION WORK? The secret to our success is in the specially designed middle plate for ES experiments. It is a PCB (printed circuit board) which can be charged with electricity. This electricity is stored in capacitors and can only be released inside of the high pressure chamber. The release of electrical current is induced by a light-sensitive switch...
