Cryo preparation
WebCryo-TEM is a technique in which a beam of electrons is transmitted through a thin and frozen section to obtain high-resolution 2D images. To obtain high-quality morphological information of cellular components, sophisticated sample preparation is required. In detail, the sample preparation for this technique is based on cryo-ultramicrotomy ...
