Workflows & Protocols: How to Isolate Individual Chromosomes with Laser Microdissection
During the first Leica Workshop in Brazil, at the Centro de Energia Nuclear na Agricultura/USP (CENA), the participants learned how to prepare samples for laser microdissection (LMD) using a cryotome.…Read article
Electron Microscopy Sample Preparation: “The Future is Cold, Dynamic and Hybrid”
In 2014, the renowned Electron Microscopy for Materials Science (EMAT) research lab at the University Antwerp, Belgium, and Leica Microsystems started a fruitful collaboration to establish a Leica…Read article
A Good Place for Materials Scientists and Mineralogists to prepare their EM Samples
In June 2014, the Institut de Minéralogie, de Physique des Matériaux et de Cosmochimie (IMPMC) of the Université Pierre et Marie Curie in Paris became a Leica reference lab for EM Sample Preparation…Read article
Workflows & Protocols: How to Use a Leica Laser Microdissection System and Qiagen Kits for Successful RNA Analysis
Laser Microdissection (LMD) allows isolating individual cells or chromosomes and is a well established technique for sample preparation prior downstream analysis of the nucleic acid content via PCR or…Read article
Critical-point Drying for the Preparation of Biological Samples for MicroCT Analysis
X-ray micro-computed tomography (micro-CT) is a routinely applied non-invasive technique for the investigation of the internal anatomy and morphology of organisms. As a result of a micro-CT scan a…Read article
Transmission Electron Microscopy Sample Preparation Protocols for the Ultrastructural Study of Cysts of Free-living Protozoa
Cysts of free-living protozoa have an impact on the ecology and epidemiology of bacteria because they may act as a transmission vector or shelter the bacteria against hash environmental conditions.…Read article
Intravenous Microinjections of Zebrafish Larvae to Study Acute Kidney Injury
We describe a technique of microinjecting the aminoglycoside, gentamicin, into 2 days post-fetilization (dpf) zebrafish larvae to induce acute kidney injury (AKI). We also describe a method for whole…Read article
High Quality Sample Preparation for EBSD Analysis by Broad Ion Beam Milling
Electron Backscatter Diffraction technique (EBSD) is known as a "surface" technique because electron diffraction is generated within a few tens of nanometers of the sample surface. Therefore, the…Read article
Correlative In-Resin Super-Resolution and Electron Microscopy Using Standard Fluorescent Proteins
We introduce a method for correlative in-resin super-resolution fluorescence and electron microscopy (EM) of biological structures in mammalian culture cells. Cryo-fixed resin embedded samples offer…Read article
Preparation of Small Disk-shaped Samples for Capacitance and Pyroelectric Current Measurements
Capacitance and pyroelectric current measurements are best suited to determine important dielectric properties of materials, e.g. the relative dielectric constant, εr, and the remnant electric…Read article
Correlative Light and Electron Microscopy – Get Your Free CLEM e-Book for Download
The urge to go deeper into the microscopic world has led researchers to combine the versatility of the light microscopy (LM) with the resolution power of the electron microscope (EM) to produce…Read article
Five Advantages of Inverted Over Upright Microscopes in Industrial Applications
With inverted microscopes, you look at samples from below since their optics are placed under the sample, with upright microscopes you look at samples from above. Traditionally, inverted microscopes…Read article
Customized Patterned Substrates for Highly Versatile Correlative Light-Scanning Electron Microscopy
Correlative light electron microscopy (CLEM) combines the advantages of light and electron microscopy, thus making it possible to follow dynamic events in living cells at nanometre resolution. Various…Read article
New Insights into Cilia and Flagella by Cryo-EM
Cilia and flagella were the first organelles to be discovered and have been studied for centuries. However, their essential role in humans and how ciliary defects cause diseases are still not well…Read article
Immersion Freezing for Cryo-Transmission Electron Microscopy: Applications
A well established usage case for cryo-TEM is three-dimensional reconstruction of isolated macromolecules, virus particles, or filaments. On one hand, these approaches are based on averaging of…Read article
