Cullen at Johns Hopkins Hospital in Baltimore also involved frozen section, but only after ...
The thin frozen sections are mounted on a glass slide, fixed immediately & briefly in liquid fixative, and stained using the similar staining techniques as traditional wax embedded sections. The advantages of this method is rapid processing time, less equipment requirement, and less need for ventilation in the laboratory.
After the development of AR, enzyme digestion was rarely used in immunohistochemistry for formalin fixed paraffin embedded tissue sections. Although enzyme digestion and antigen retrieval target the same problem in immunohistochemistry, these two techniques differs in both the mode of action and effectiveness, warranting distinct nomenclature.

Frozen section procedure: water-rich tissues are hardened by freezing and cut in the frozen state with a freezing microtome or microtome-cryostat; sections are stained and examined with a light microscope. This technique is much faster than traditional histology (5 minutes vs 16 hours) and is used in conjunction with medical procedures to ...

Similar to the frozen section procedure employed in medicine, cryosectioning is a method to rapidly freeze, cut, and mount sections of tissue for histology. The tissue is usually sectioned on a cryostat or freezing microtome. [12] The frozen sections are mounted on a glass slide and may be stained to enhance the contrast between different tissues.
