Freeze Fracture and Freeze Etching

2013
Freeze fracture depends on the property of frozen tissues or cells, when cracked open, to split along the hydrophobic interior of membranes, thus revealing broad panoramas of membrane interior. These large panoramas reveal the three-dimensional contours of membranes making the methods well suited to studying changes in membrane architecture.

Freeze‐drying using vacuum‐induced surface freezing

Journal of Pharmaceutical Sciences, 2002
A method of freezing during freeze-drying, which avoids undercooling of a solution and allows growth of large, dendritic ice crystals, was investigated. Aqueous solutions of mannitol, sucrose, or glycine were placed under a chamber vacuum of approximately 1 mbar at a shelf temperature of +10 degrees C.

Freeze-Etching Simplified

Proceedings, annual meeting, Electron Microscopy Society of America, 1968
Freeze-etching, as a tool in the preparation of biological specimens for electron microscopy, has seen relatively little use since it was introduced in 1957. The involved procedure, originally described, and, until recently, the cost of special equipment, must certainly have played a part in the failure of freeze-etching to become a commonly used ...

Freezing and Freeze-Drying of Bull Spermatozoa

American Journal of Physiology-Legacy Content, 1957
The possible dependance of survival upon the time spermatozoa are in contact with the protective substance glycerol, prior to exposure to low temperatures, was investigated. Pretreatment for 5 minutes provided at least as much protection as 18 hours.
