The frozen section procedure is a pathological laboratory procedure to perform rapid microscopic analysis of a specimen. It is used most often in oncological surgery. [1] The technical name for this procedure is cryosection. The microtome device that cold cuts thin blocks of frozen tissue is called a cryotome. [2]
Frozen section procedure: tissue embedded in optimal cutting temperature compound, mounted on a chuck in a cryostat and ready for section production. Optimal cutting temperature compound (OCT compound) is used to embed tissue samples prior to frozen sectioning on a microtome-cryostat. This process is undertaken so as to mount slices (sections ...
In cryo-sectioning, frozen blocks of cells or tissue are sectioned into thin samples with a cryo-microtome. [11] In FIB-milling, plunge-frozen samples are exposed to a focused beam of ions, typically gallium , that precisely whittle away material from the top and bottom of a sample, leaving a thin lamella suitable for cryoET imaging.
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 ...
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. The cryostat is usually a stationary upright freezer, with an external wheel for rotating ...
