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…
Each Atom Counts: Protect Your Samples Prior to FIB Processing
Application Note for Leica EM ACE600 - Focused ion beam (FIB) technology has become an indispensable tool for site-specific TEM sample preparation. It allows to extract electron transparent specimens…
Bacteria Protocol - Critical Point Drying of E. coli for SEM
Application Note for Leica EM CPD300 - Critical point drying of E. coli with subsequent platinum / palladium coating and SEM analysis. Sample was inserted into a filter disc (Pore size: 16 - 40 μm)…
Epoxy Resin Embedding of Animal and Human Tissues for Pathological Diagnosis and Research
Application Note for Leica EM AMW - The tissues were fixed in the modified Karnovsky fixative generally by immersion overnight (at minimum 4h at room temperature). Then pieces of approx. 1mm3 were cut…
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…
Human Blood Cells Protocol
Application Note for Leica EM CPD300 - Life Science Research. Species: Human (Homo sapiens)
Critical point drying of human blood with subsequent platinum / palladium coating and SEM analysis.
Brief Introduction to Contrasting for EM Sample Preparation
Since the contrast in the electron microscope depends primarily on the differences in the electron density of the organic molecules in the cell, the efficiency of a stain is determined by the atomic…
Carbon Thickness Evaluation in Electron Microscopy
The coating layers applied and used for electron microscopy imaging are commonly controlled and measured by quartz crystals. These crystals oscillate with a certain frequency (around 6 megahertz when…
