Fixation fixing
WebHeat fixation. Ether saline (0.85%) or 10% formal saline is used. 20 to 40 ml is heated below the boiling point then the tissue slice (3 to 5mm thick) is placed in hot fluid & heating is continued for 1 min until tissue floats to the surface. After this it is cooled quickly in water & mounted on microtome. 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.
