2. Fixation (histology) - Wikipedia

   en.wikipedia.org/wiki/Fixation_(histology)

   The sample of tissue is immersed in fixative solution for a set period of time. The fixative solution must have a volume at least 10 times greater than the volume of the tissue. [6] In order for fixation to be successful, the fixative must diffuse throughout the entire tissue, so tissue size and density, as well as type of fixative must be ...

3. Histology - Wikipedia

   en.wikipedia.org/wiki/Histology

   The field of histology that includes the preparation of tissues for microscopic examination is known as histotechnology. Job titles for the trained personnel who prepare histological specimens for examination are numerous and include histotechnicians, histotechnologists, [ 11 ] histology technicians and technologists, medical laboratory ...

4. Frozen section procedure - Wikipedia

   en.wikipedia.org/wiki/Frozen_section_procedure

   The frozen section procedure as practiced today in medical laboratories is based on the description by Dr Louis B. Wilson in 1905. Wilson developed the technique from earlier reports at the request of Dr William Mayo, surgeon and one of the founders of the Mayo Clinic [3] Earlier reports by Dr Thomas S. Cullen at Johns Hopkins Hospital in Baltimore also involved frozen section, but only after ...

5. Microtome - Wikipedia

   en.wikipedia.org/wiki/Microtome

   This technique is much faster than traditional histology (5 minutes vs 16 hours) and is used in conjunction with medical procedures to achieve a quick diagnosis. Cryosections can also be used in immunohistochemistry as freezing tissue stops degradation of tissue faster than using a fixative and does not alter or mask its chemical composition as ...

6. H&E stain - Wikipedia

   en.wikipedia.org/wiki/H&E_stain

   The H&E staining procedure is the principal stain in histology [3] [7] [2] [5] in part because it can be done quickly, [7] is not expensive, and stains tissues in such a way that a considerable amount of microscopic anatomy [9] [10] is revealed, [7] [5] [4] and can be used to diagnose a wide range of histopathologic conditions. [8]

7. 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 ...
