WebCryogenic electron tomography (cryo-ET) is an imaging technique used to obtain high resolution 3D reconstructions of biomolecules. In cryo-ET a vitrified sample is imaged in a TEM as it is tilted from approximately -60⁰ to +60⁰. This results in a series of 2D images that can be combined to reconstruct a 3D image, a so-called tomogram. WebVolume EM techniques such as serial section TEM, automated tape-collecting ultramicrotome, focused ion-beam scanning electron microscopy and SBEM (microtome serial block-face scanning electron microscopy) are the techniques that provide sufficient resolution to resolve ultrastructural details such as synapses and provides sufficient field …
