However, these proteins are also present in numerous other organisms. These "other" TH-producing organisms are the focus of this chapter. They include many types of animals such as noninsect arthropods (spiders,
Prevention of ice crystal growth by antifreeze proteins. (A) Crystal growth in water molecules adds preferentially onto the circumference to form a larger, circular, flat crystal. (B) Water plus a purified AFP, a glucanase, from winter rye; the crystal growth around the circumference is ...
5.3.3 Ice Nucleation Proteins Ice nucleation in bacteria is ascribed to the presence of a protein in the outer cell membrane where it acts as a template for ice nucleation. In this way the desiccation is prevented, the water source near cell surface is separated, ice particles are spread out...
The cryoprotective solution contains glycerol and antifreeze proteins, both of which are found in freeze tolerant animals. Whole rat livers were frozen to -3 degrees C, maintained at that temperature for 6 hours and then warmed to 37 degrees C. Post thawing bile production and microscopic ...
Proteins that safeguard animals and plants from freezing under extremely cold temperatures could be the key to cementing the sustainability of future infrastructure.Wil Srubar III.

DAFP-1 and DAFP-4 are two of the four major antifreeze proteins in the hemolymph in D. canadensis. They interact with one another and thermal hysteresis activity is increased synergistically when tested at physiological concentrations at a 1:1 ratio in vitro (Wang and Duman, 2005). In a ...
Antifreeze proteins (AFP) have the potential for improving sperm cryopreservation. We have applied Type III antifreeze protein (AFP3) on the cryopreservation of spermatozoa from broiler breeder roosters, aiming to enhance post-thawing quality and fertility. Semen was extended at 37°C in Lake's ext...
