  2. Frozen section procedure - Wikipedia

    en.wikipedia.org/wiki/Frozen_section_procedure

    The frozen section procedure is a pathological laboratory procedure to perform rapid microscopic analysis of a specimen. It is used most often in oncological surgery. [1] The technical name for this procedure is cryosection. The microtome device that cold cuts thin blocks of frozen tissue is called a cryotome. [2]

  3. Microtome - Wikipedia

    en.wikipedia.org/wiki/Microtome

    Frozen section procedure: water-rich tissues are hardened by freezing and cut in the frozen state with a freezing microtome or microtome-cryostat; sections are stained and examined with a light microscope. This technique is much faster than traditional histology (5 minutes vs 16 hours) and is used in conjunction with medical procedures to ...

  4. Frozen tissue array - Wikipedia

    en.wikipedia.org/wiki/Frozen_tissue_array

    Then all the frozen tissue cores are inserted in a recipient OCT frozen block in a precisely spaced, array pattern. Sections from this block are cut using a cryostat, mounted on a microscope slide and then analyzed by any method of standard histological analysis. Each frozen tissue array block can be cut into 100–500 sections, which can be ...

  5. Histopathology - Wikipedia

    en.wikipedia.org/wiki/Histopathology

    The tissue is then prepared for viewing under a microscope using either chemical fixation or frozen section. If a large sample is provided e.g. from a surgical procedure then a pathologist looks at the tissue sample and selects the part most likely to yield a useful and accurate diagnosis - this part is removed for examination in a process ...

  6. Fluorescence in situ hybridization - Wikipedia

    en.wikipedia.org/wiki/Fluorescence_in_situ...

    The process is done in 3 main procedures: tissue preparation (pre-hybridization), hybridization, and washing (post-hybridization). The tissue preparation starts by collecting the appropriate tissue sections to perform RNA FISH. First, cells, circulating tumor cells (CTCs), formalin-fixed paraffin-embedded (FFPE), or frozen tissue sections are ...

  7. Histology - Wikipedia

    en.wikipedia.org/wiki/Histology

    Similar to the frozen section procedure employed in medicine, cryosectioning is a method to rapidly freeze, cut, and mount sections of tissue for histology. The tissue is usually sectioned on a cryostat or freezing microtome. [12] The frozen sections are mounted on a glass slide and may be stained to enhance the contrast between different tissues.

  8. Cryostat - Wikipedia

    en.wikipedia.org/wiki/Cryostat

    Cryostats are used in medicine to cut histological slides. They are usually used in a process called frozen section histology (see Frozen section procedure). The cryostat is essentially an ultrafine "deli-slicer", called a microtome, placed in a freezer. The cryostat is usually a stationary upright freezer, with an external wheel for rotating ...

  9. Optimal cutting temperature compound - Wikipedia

    en.wikipedia.org/wiki/Optimal_cutting...

    Frozen section procedure: tissue embedded in optimal cutting temperature compound, mounted on a chuck in a cryostat and ready for section production. Optimal cutting temperature (OCT) compound is used to embed tissue samples prior to frozen sectioning on a microtome-cryostat. This process is undertaken so as to mount slices (sections) of a ...
