  2. Fixation (histology) - Wikipedia

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

    In the fields of histology, pathology, and cell biology, fixation is the preservation of biological tissues from decay due to autolysis or putrefaction.It terminates any ongoing biochemical reactions and may also increase the treated tissues' mechanical strength or stability.

  3. Diff-Quik - Wikipedia

    en.wikipedia.org/wiki/Diff-Quik

    Diff-Quik may be utilized on material which is air-dried prior to alcohol fixation rather than immersed immediately (i.e. "wet-fixed"), although immediate alcohol fixation results in improved microscopic detail. [2] [3] [6]

  4. Zenker's fixative - Wikipedia

    en.wikipedia.org/wiki/Zenker's_fixative

    Zenker's fixative is a rapid-acting fixative for animal tissues. It is employed to prepare specimens of animal or vegetable tissues for microscopic study. It provides excellent fixation of nuclear chromatin, connective tissue fibers and some cytoplasmic features, but does not preserve delicate cytoplasmic organelles such as mitochondria.

  5. Cryofixation - Wikipedia

    en.wikipedia.org/wiki/Cryofixation

    Cryofixation is a technique for fixation or stabilisation of biological materials as the first step in specimen preparation for the electron microscopy and cryo-electron microscopy. [1] Typical specimens for cryofixation include small samples of plant or animal tissue , cell suspensions of microorganisms or cultured cells , suspensions of ...

  6. Microtechnique - Wikipedia

    en.wikipedia.org/wiki/Microtechnique

    Microtechnique is an aggregate of methods used to prepare micro-objects for studying. [1] It is currently being employed in many fields in life science. Two well-known branches of microtechnique are botanical (plant) microtechnique and zoological (animal) microtechnique.

  7. Immunohistochemistry - Wikipedia

    en.wikipedia.org/wiki/Immunohistochemistry

    Immunohistochemistry can be performed on tissue that has been fixed and embedded in paraffin, but also cryopreservated (frozen) tissue.Based on the way the tissue is preserved, there are different steps to prepare the tissue for immunohistochemistry, but the general method includes proper fixation, antigen retrieval incubation with primary antibody, then incubation with secondary antibody.

  8. Histopathology - Wikipedia

    en.wikipedia.org/wiki/Histopathology

    The most commonly used stain in histology is a combination of hematoxylin and eosin (often abbreviated H&E). Hematoxylin is used to stain nuclei blue, while eosin stains the cytoplasm and the extracellular connective tissue matrix of most cells pink. There are hundreds of various other techniques which have been used to selectively stain cells.

  9. Histology - Wikipedia

    en.wikipedia.org/wiki/Histology

    Histologic specimen being placed on the stage of an optical microscope Human lung tissue stained with hematoxylin and eosin as seen under a microscope. Histology, [help 1] also known as microscopic anatomy or microanatomy, [1] is the branch of biology that studies the microscopic anatomy of biological tissues.
