About the Krios

The FEI Titan Krios™ cryo-Transmission Electron Microscope is a state-of-the-art, dedicated imaging robot, optimized for both high-resolution 3D imaging of proteins and macromolecular assemblies, and high-resolution, dual-axis, cellular tomography. Its revolutionary cryo-based technology and stability permits a full range of semi-automated applications, including: 2D electron crystallography, single particle analysis, cryo-electron microscopy, and dual-axis cellular tomography of frozen hydrated samples. Cryo-techniques preserve sample integrity by maintaining the sample in its natural condition and state.

One of 50 or fewer high-resolution, cryo-electron microscopes in the world.
Requires a specialized environment: low vibration and heat differential tolerance, an absence of electromagnetic currents.
Achieves atomic resolution data.
Good for achieving high-resolution, high-quality optics for cryo samples, as opposed to fixed samples. 
Has low-dose capabilities, achieves balance between showing good information and destroying the sample.

ABOUT THE FEI Tecnai™ with iCORR™

The most critical "tie point" between imaging modalities is between fluorescence (FM) and electron microscopy (EM), with EM providing Angstrom to nanometer resolution information about molecular ultrastructure and FM providing nanometer to micrometer resolution information about functional molecular complexes.  Scientists from FEI and the Biomolecular Imaging program at Utrecht University have developed novel sample fixation and staining procedures for the Tecnai™ with iCorr™ that preserve both ultrastructural and molecular features for FM and transmission electron microscopy (TEM) and reduce sample preparation times.

One of two in the world (the other is located in the Netherlands); this one is the first to be commercially available.
Correlates light microscopy and electron microscopy. Uses light microscopy to find a rare cell or event and uses electron microscopy to study that event.
Ideal for identifying rare cells, events in a large sample, such as 1 in 10,000 events or cells.
