Preferred term

Freeze Etching  

Type

  • Topical Descriptor

Broader concept

Note

  • do not confuse with FREEZE FRACTURING (wherein a cryoprotectant is used)

Scope note

  • A replica technique in which cells are frozen to a very low temperature and cracked with a knife blade to expose the interior surfaces of the cells or cell membranes. The cracked cell surfaces are then freeze-dried to expose their constituents. The surfaces are now ready for shadowing to be viewed using an electron microscope. This method differs from freeze-fracturing in that no cryoprotectant is used and, thus, allows for the sublimation of water during the freeze-drying process to etch the surfaces.
