Biological research is increasingly focusing on unraveling interactive processes and pathways at the molecular level. To obtain the most biologically relevant information, samples must be observed in 3D and in their native, hydrated states. For this, high-resolution cryo transmission electron microscopy (cryo-TEM) is indispensable, as it provides snapshots of molecular structures frozen within a vitrified aqueous environment.
Cryo-electron microscopy single particle analysis (cryo-EM SPA) in particular has become an established technique for 3D image creation based on cryo-TEM data. This is done by averaging large amounts of well-aligned 2D images into a 3D reconstruction.
Thermo Scientific EPU 2 Software is an automated screening and data acquisition tool that has been developed to efficiently collect these large, high-quality datasets. It provides a holistic solution for both identifying suitable areas for data collection and acquiring the necessary number of high-resolution images for 3D reconstruction and processing.
Key Features

Cryo-Tomography
Cryo-electron tomography (cryo-ET) delivers both structural information about individual proteins as well as their spatial arrangements within the cell. This makes it a truly unique technique and also explains why the method has such an enormous potential for cell biology. Cryo-ET can bridge the gap between light microscopy and near-atomic-resolution techniques like single-particle analysis.
Single Particle Analysis
Single particle analysis (SPA) is a cryo-electron microscopy technique that enables structural characterization at near-atomic resolutions, unraveling dynamic biological processes and the structure of biomolecular complexes/assemblies.
