Basic aspects of frozen storage of semen
Animal Reproduction Science, 2000Basic concepts of cryopreservation and the causes of cryoinjury are reviewed. The possible roles of cryoprotectants and additives are considered in the context of their putative interactions with the sperm plasma membrane. Modern approaches to the laboratory assessment of spermatozoa after freeze-thawing are also briefly discussed.

Storage of Frozen Rosefish Fillets
Journal of the Fisheries Research Board of Canada, 1956Taste panel assessments of taste, texture, and grade of cooked samples, examination prior to cooking, and analyses of soluble actomyosin and of fat spoilage on frozen rosefish (Sebastes marinus) fillets, with and without treatment with ascorbic acid, stored at −10°F. (−23 °C.) and +10°F.

Long-Term Frozen Storage of Choanoflagellate Cultures
Cold Spring Harbor Protocols, 2009INTRODUCTIONChoanoflagellates are heterotrophic nanoflagellates: small, colorless protozoa that are present in marine and freshwater environments as well as in hydrated soils. Because they are the closest living relatives of the metazoa, the study of their cell biology and genomes promises to provide new insights into metazoan ancestry and origins ...

Frozen Storage of Tritrichomonas foetus for 5.6 Years*
The Journal of Protozoology, 1966SYNOPSIS. Tritrichomonas foetus was cultivated in Diamond's medium without phosphates or agar; 10% glycerol was added to the medium and the protozoa were frozen slowly and stored at −28 or −95 C. About half of the trichomonads died within the first day at either temperature. Thereafter, they continued to die off slowly during storage at −28, and none

The Effect of Storage Temperature on the Stability of Frozen Erythrocytes
Cryobiology, 1995A systematic study on the stability of frozen erythrocytes was performed. Washed and concentrated erythrocytes were mixed with an equal volume of cryoprotective solution containing 24% (w/w) hydroxyethyl starch (HES) and 60 mmol/liter NaCl according to an established protocol.

Rapid freezing, frozen storage and the tenderness of lamb
Meat Science, 1980Cold-shortening in pre-rigor lamb can be prevented by freezing carcasses very rapidly in less than four hours. Thaw-shortening can also be prevented by storing the carcasses for a period (> 10 days) in the frozen state (- 12°C). By this simple combination of rapid freezing and frozen storage, the hazard of toughness development from cold- and thaw ...

Nutrient medium and frozen storage of human lymphocytes
Cryobiology, 1975Abstract 1. 1. Lymphocytes to be used for tissue typing procedures can be stored at room temperature in a nutrient medium for periods of up to 3 wk without an intervening change of fluid medium. 2. 2. Fresh or nutrient medium stored lymphocytes can be frozen in bulk quantities until they are required for tissue typing studies, and/or 3. 3.

Freezing and Frozen-Food Storage
1997Food freezing is the preservation process that depends on the reduction of product temperature to levels well below the temperature at which ice crystals begin to form within the food. By reducing the temperature of the product to -10 to -20°C, the normal reactions that cause deterioration of foods are reduced to negligible or minimal rates.

Storage of bovine semen in liquid and frozen state
Animal Reproduction Science, 2000This review describes the historical and current methods used for storage of bovine semen. The essential physiological differences between liquid and frozen semen, their relative advantages and disadvantages are addressed, and the current state of technology, the procedures used, their merits and future possibilities are also discussed.

Deamidation of Insulin during Storage in Frozen State
Diabetes, 1966Insulin dissolved in weak HC1 (5×10−3M) appears to undergo progressive deamidation on storage at –15° C. Some commercial solutions of insulin contain quite significant amounts of desamido components. The possibility that desamido insulin may contribute to insulin antigenicity is considered.
