Tissue processing is a fundamental procedure in biological and medical research.

The first step in tissue processing is fixation. Fixatives like formaldehyde are used to preserve the tissue's structure by cross - linking proteins. This stops autolysis and degradation, maintaining the tissue as close to its original state as possible. For example, in a surgical biopsy, proper fixation is crucial for accurate diagnosis.

Next comes dehydration. Since most embedding media are not water - soluble, the water in the tissue is replaced with alcohols, usually ethanol. A gradual increase in ethanol concentration is carried out to prevent tissue distortion.

Clearing follows dehydration. Commonly, xylene is used to remove alcohol and make the tissue more transparent for embedding. However, due to its toxicity, safety measures are necessary.

Embedding is then done. Paraffin is the most popular embedding medium. The tissue is placed in molten paraffin, which solidifies around it, creating a block that can be sliced. Resins are also used in some cases, especially for electron microscopy when ultrastructural details need better preservation.

Finally, the embedded tissue is sectioned using a microtome and mounted on glass slides. These slides are then ready for further analysis, such as histological staining or immunohistochemistry. In conclusion, tissue processing is essential for obtaining high - quality tissue samples for various scientific and medical investigations.
