Bridging Structure and Dynamics at the Nanoscale through Optogenetics and Electrical Stimulation
Nanoscale ultrastructural information is typically obtained by means of static imaging of a fixed and processed specimen. However, this is only a snapshot of one moment within a dynamic system in…
Expanding the Limits of Electron Microscopy Sample Preparation
Capturing the intricate changes in fine structure or in cell dynamics with conventional cryo solutions can be challenging sometimes. Leica Microsystems has developed a new cryo platform, the Leica EM…
Practical Applications of Broad Ion Beam Milling
Mechanical polishing can be time consuming and frustrating. It can also introduce unwanted artifacts when preparing cross-sectioned samples for electron backscatter diffraction (EBSD) in the scanning…
Interview with Dr. Shigeki Watanabe on Research in Synaptic Membrane Dynamics
Dr. Shigeki Watanabe, principle investigator of the department of Cell Biology at the Johns Hopkins University School of Medicine in Baltimore, held a workshop in Zürich, Switzerland on methods to…
Cryo-Electron Microscopy of Vitreous Sections (CEMOVIS) of Yeast
Application Note for Leica EM HPM100 - The sections are of yeast frozen with a Leica HPM100 high pressure freezer in the copper tube system, the cell paste was mixed with a pH 6.5 MES/dextran buffer…
Video Tutorials: Filling and Assembling of Different Carriers for High-Pressure Freezing
High pressure freezing (HPF) is a cryo-fixation method primarily for biological samples, but also for a variety of non-biological materials. It is a technique that yields optimal preservation in many…
Brief Introduction to Freeze Fracture and Etching
Freeze fracture describes the technique of breaking a frozen specimen to reveal internal structures. Freeze etching is the sublimation of surface ice under vacuum to reveal details of the fractured…
Brief Introduction to Freeze Substitution
Freeze-substitution is a process of dehydration, performed at temperatures low enough to avoid the formation of ice crystals and to circumvent the damaging effects observed after ambient-temperature…
Thermodynamic Considerations Regarding the LN2 in a High Pressure Freezer
Employing liquid nitrogen (LN2) as a coolant in the complex process of high pressure freezing raises certain considerations regarding phase transition not only of the liquid sample to be frozen but…
