Improved tree-ring visualization using autofluorescence
Autofluorescence can be a very practical tool for the visualization of growth rings in wood, especially when these structures are hard to distinguish, like in tropical trees. Tree rings are largely…Read article
Variety of RNAs in Peripheral Blood Cells, Plasma, and Plasma Fractions
Human peripheral blood contains RNA in cells and in extracellular membrane vesicles, microvesicles and exosomes, as well as in cell-free ribonucleoproteins. Circulating mRNAs and noncoding RNAs, being…Read article
Translation Microscopy (TRAM) for Super-Resolution Imaging
Super-resolution microscopy is transforming our understanding of biology but accessibility is limited by its technical complexity, high costs and the requirement for bespoke sample preparation. We…Read article
TEM Sample Preparation Made Easy - Prepare TEM Specimen by Broad Beam Argon Ion Milling
Quantitative and analytical analysis at high spatial resolution places stringent demands on the quality of the produced TEM specimens. Pristine and high-quality samples are indispensible for atomic…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
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
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
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
Imaging Pheromone Sensing in a Mouse Vomeronasal Acute Tissue Slice Preparation
In mice, the ability to detect pheromones is principally mediated by the vomeronasal organ (VNO). Here, an acute tissue slice preparation of VNO for performing calcium imaging is described. This…Read article
Rapid Immunohistochemical Diagnosis of Tobacco Mosaic Virus Disease by Microwave-assisted Plant Sample Preparation
Immunoelectron microscopy is a powerful method to diagnose viral diseases and to study the distribution of the viral agent within plant cells and tissues. Nevertheless, current protocols for the…Read article
Immersion Freezing of Suspended Particles and Cells for Cryo-Electron Microscopy
Immersion freezing of thin aqueous specimens is an essential preparation technique for cryo-transmission electron microscopy (cryo-TEM), aiming to preserve fragile biological structures such as…Read article
Microwave Assisted Rapid Diagnosis of Plant Virus Diseases by Transmission Electron Microscopy
Investigations of ultrastructural changes induced by viruses are often necessary to clearly identify viral diseases in plants. With conventional sample preparation for transmission electron microscopy…Read article
Focussed Ion Beam Milling and Scanning Electron Microscopy of Brain Tissue
This protocol describes how biological samples, like brain tissue, can be imaged in three dimensions using the focussed ion beam/scanning electron microscope (FIB/SEM). The samples are fixed with…Read article
Advanced Correlative Light/Electron Microscopy: Current Methods and New Developments Using Tokuyasu Cryosections
Microscopy is an essential tool for analysis of cellular structures and function. With the advent of new fluorescent probes and super-resolution light microscopy techniques, the study of dynamic…Read article
