Exempel på antifreeze

• Survival of mouse blastocysts slow cooled in propanediol or ethylene glycol is influenced by the thawing procedure, sucrose and antifreeze proteins.

• These various antifreeze molecules disrupt or arrest the growth of ice crystals in the animal's body and hence prevent freezing.

• Antifreeze protein modulates cell survival during cryopreservation: mediation through influence on ice crystal growth.

• Other survival strategies include the synthesis of stress proteins, reduction in cell size, dormancy or sporulation, or the use of antifreeze intracellular solutions (elaborated on below).

• Chapter 4 examines the remarkable story of the evolution of groups of glycol-proteins and peptides that act as antifreezes, allowing fish to live at polar water temperatures.

• The addition of antifreeze will not impair the efficacy of disinfectants during frost.

• There seems to be a very strong case for insisting that this particular material, antifreeze solution, should be in marked containers.

• Sometimes counterfeit medicines for simple illnesses such as coughs can even cause umpteen deaths, as they have had toxic chemicals added that are normally used in products such as antifreeze.
