- Tissue fixation is a critical step in the preparation of histological sections12. The goal of fixation is to create the matrix of cross-links to immobilize proteins that make up the tissue3. The optimal time for fixation will vary between fixatives, tissue type and size2. The technique of getting fixed tissue into paraffin is called tissue processing4. Tissue processing is designed to remove all extractable water from the tissue, replacing it with a support medium that provides sufficient rigidity to enable sectioning of the tissue without damage or distortion4.

If it is not carried out under optimal conditions or if fixation is delayed, a tissue specimen can be irreversibly damaged compromising morphological and histochemical information.

As our body is made up of all kinds of proteins and lipids, carbohydrates, etc., creating a matrix of cross-links is incredibly important. Once we do that, we stop autolysis which is the self-destruction of the tissue.www.leicabiosystems.com/knowledge-pathway/pro…The technique of getting fixed tissue into paraffin is called tissue processing Tissue processing is designed to remove all extractable water from the tissue, replacing it with a support medium that provides sufficient rigidity to enable sectioning of the tissue without damage or distortionwww.labtestsguide.com/tissue-processing - People also ask

Fixation (histology) - Wikipedia
In performing their protective role, fixatives denature proteins by coagulation, by forming additive compounds, or by a combination of coagulation and additive processes. A compound that adds chemically to macromolecules stabilizes structure most effectively if it is able to combine with parts of two different macromolecules, an effect known as cross-linking. Fixation of tissue is done for several reasons. One reason is to kill the tissue so that postmortem decay (autolysis and put…
