CryoSTEM tomography in biology

Abstract

Electron cryo-tomography using the scanning transmission modality (STEM)enables 3D reconstruction of unstained, vitrified specimens as thick as 1 μm or more. Contrast is related to mass/thickness and atomic number, providing quantifiable chemical characterization and mass mapping of intact prokaryotic and eukaryotic cells. Energy dispersive X-ray spectroscopy by STEM provides a simple, on-the-spot chemical identification of the elemental composition in sub-cellular organic bodies or mineral deposits. This chapter provides basic background and practical information for performing cryo-STEM tomography on vitrified biological cells.
