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 Frozen Maize Tissue
1994Most protocols for the isolation of DNA and RNA require grinding frozen tissue to a fine powder prior to extraction. Several of the protocols in this book include a short description of how maize tissue should be ground for particular purposes. In this section an efficient system for the storage of frozen ground maize tissue is described.
