Correlative Light Electron Microscopy (CLEM)
CLEM (Correlative Light Electron Microscopy) combines the capabilities of two typically separate microscopy platforms: light (or fluorescent) microscopy (LM) and electron microscopy (EM). The advantage of LM is that it can provide wide field images of whole, often living, cells, but its resolution is limited. The advantage of EM is that it can provide much higher resolution images, up to molecular dimensions, but only over specific regions of a cell at a time and not in living cells. CLEM combines the advantages of both techniques, allowing scientists to spot cellular structures and processes of interest in whole cell images with LM and then zoom in for a closer look with EM. This dual examination provides valuable complementary and often unique information.

Correlative Cryo-Fluorescence and Cryo-Scanning Electron Microscopy as a Straightforward Tool to Study Host-Pathogen Interactions
Correlative light and electron microscopy is an imaging technique that enables identification and targeting of fluorescently tagged structures with subsequent imaging at near-to-nanometer resolution. We established a novel correlative cryo-fluorescence microscopy and cryo-scanning electron…Read article -
Imaging of Host Cell-bacteria Interactions using Correlative Microscopy under Cryo-conditions
Pathogenic bacteria have developed intriguing strategies to establish and promote infections in their respective hosts. Most bacterial pathogens initiate infectious diseases by adhering to host cells surface. Knowledge of the interplay between the pathogenic organism and the host cells can provide…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 superior structural preservation, performing in-resin super-resolution, however, remains a challenge.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 understood. Cryo-EM has recently shed new light on their inner workings and solved some long-standing…Read article -
ICln: A New Regulator of Non-Erythroid 4.1R Localisation and Function
To optimise the efficiency of cell machinery, cells can use the same protein (often called a hub protein) to participate in different cell functions by simply changing its target molecules. There are large data sets describing protein-protein interactions ("interactome") but they frequently fail to…Read article -
A Precise and Rapid Mapping Protocol for Correlative Light and Electron Microscopy of small invertebrate organisms
CLEM (correlative live cell and electronmicroscopy) seeks to bridge the data acquired with different imaging strategies, typically between light microscopy and electron microscopy. It has been successfully applied in cell cultures, although its use in multicellular systems is hampered by…Read article -
Brief Introduction to High-Pressure Freezing
Water is the most abundant cellular constituent and therefore important for preserving cellular ultra-structure. Currently the only way to fix cellular constituents without introducing significant structural alterations is by cryo-fixation. There are currently two common methods employed; plunge…Read article -
Postlipolytic Insulin-dependent Remodeling of Micro Lipid Droplets in Adipocytes
Despite the lipolysis–lipogenesis cycle being a fundamental process in adipocyte biology, very little is known about the morphological changes that occur during this process. The remodeling of lipid droplets to form micro lipid droplets (mLDs) is a striking feature of lipolysis in adipocytes, but…Read article -
A Genetically Encoded Tag for Correlated Light and Electron Microscopy of Intact Cells, Tissues, and Organisms
