What is meant by Cryosection?
Filters. (biology) To section biological tissue using a cryostat. A section of tissue so obtained. noun.
How do you perform a Cryosection?
Sectioning in Brief. Place your prepared tissue block within the cryostat chamber (Figure 1) for 30-60 minutes prior to beginning your sectioning, to allow the tissue to acclimate to -200C. You should begin your cryosectioning practice with either non-essential tissue or a block of O.C.T.
What is the purpose of Cryosectioning?
The purpose of Cryosection is to deliver a rapid diagnosis of a cancerous tumor or mass. Since the procedure involves the rapid freezing of the tissue sample, it minimizes any morphological damage. It’s also excellent for detecting antigens.
What is cryostat sectioning?
Cryostats are used in medicine to cut histological slides. They are usually used in a process called frozen section histology (see Frozen section procedure). The cryostat is essentially an ultrafine “deli-slicer”, called a microtome, placed in a freezer.
What is a freezing microtome?
A microtome in which the tissue sample is frozen and maintained in a frozen state with liquid carbon dioxide. It is useful for (rapidly) obtaining sections of unfixed soft tissue.
How do you store Cryosections?
Regarding the storage of the sections, I would prefer to arrange the slides in a storage box and keep the storage box in a plastic bag. If you are storing your sections for longer duration, It would be a good idea to leave two open tubes of frozen MilliQ water in the bag to avoid the water loss from sections.
What are the types of Microtomes?
There are different types of microtomes:
- hand microtome.
- rotational microtome.
- sledge microtome.
- cryostat (freezing microtome)
- ultramicrotome.
What is a fresh specimen?
Test Name Fresh Specimens Specimen Type. Tissue that is required to be sent to the laboratory fresh for further testing such as frozen section, micro/culture, flow cytometry or karyotyping.

Why are frozen sections used in cryosectioning procedures?
Rapid freezing reduces ice crystal formation and minimizes morphological damage. Frozen sections may be used for a variety of procedures, including immunochemistry, enzymatic detection, and in situ hybridization. A protocol for cryosectioning is presented here.
Why are cryosectioning tissues better than paraffin-embedded tissues?
Cryosectioning tissues INTRODUCTIONCryosections are rapidly and relatively easily prepared prior to fixation, and they provide a good system for visualizing fine details of the cell. Although cryosections are physically less stable than paraffin- or resin-embedded sections, they are generally superior for the preservation …
Why is air dry used in cryosectioning procedure?
Some researchers air-dry the section onto the slide at air temperature to maximize adherence before fixation. However, this technique has a disadvantage where the surface tension forces distortion of the cells resulting in the loss of high-resolution detail. It can also lead to changes in the results of immunostaining.
