Importance of microtome in histopathology
WitrynaIn this technique, tissues are fixed, and embedded in wax. This makes the tissue hard, and much easier to cut sections from. The sections are then stained, and examined with the light microscope. 1. Fixation: Square tissue blocks (about 1cm in each dimension), or whole organs, are fixed by chemical fixation: WitrynaA microtome is used to slice extremely thin tissue sections off the block in the form of a ribbon, following histochemical staining (typically haematoxylin and eosin - “HE stain”) to provide contrast to tissue sections, making tissue structures better visible and easier to evaluate. In certain cases immunohistochemical stainings (IHC), such ...
