摘要： Polyvinyl alcohol and related compounds are provided that inhibit the freezing of water and water solutions. These synthetic compounds preferentially bind and inhibit ice nucleating surfaces in a manner similar to natural antifreeze proteins. The resulting inhibition allows water and water solutions to supercool without ice formation to temperatures below the thermodynamic freezing point. The freezing inhibition occurs at concentrations as small as one part per million, although concentrations up to one part per hundred are preferred. These polyvinyl alcohol additives are very useful for enhancing the performance of antifreeze formulations, biological cryopreservation solutions, and for preventing frost damage to plants and other industrial products and processes.

摘要： Linear polymers of glycerol can prevent or delay ice nucleation in a variety of contexts. Polyglycerol can also be employed in combination with other ice control agents, such as polyvinyl alcohol/polyvinyl acetate copolymers and antifreeze proteins, to provide antinucleation effects that are superior to those of either polyglycerol or the co-antinucleator alone. Polyglycerol has a number of advantageous physical and toxicological properties, such as extreme water solubility, non-toxicity to human beings, non-toxicity to animal tissues and organs in vitro even at extreme concentrations, minimal foaming tendency, minimal retention on hydrophobic surfaces, and stability in solution without the need for periodic heating to reactivate its antinucleation properties.

摘要： Methods and compositions are provided for the cryopreservation of human organs and tissues. In certain embodiments, Step 1 comprises perfusion with a vitrifiable cryoprotectant solution at a temperature above −10° C. for a time insufficient for the approximate osmotic equilibration of the organ with the solution, followed by cooling the organ to below −10° C. by perfusion with said solution at a reduced temperature. In certain embodiments, Step 2 comprises increasing the concentration of cryoprotectant further at a temperature from −10 to −40° C. In certain embodiments, Step 3 comprises cooling and vitrifying the organ, rewarming it, and perfusing the organ with a vitrifiable concentration of cryoprotectant whose temperature is either raised gradually or is held at ≧−15° C. Compositions are provided that allow safe organ perfusion with vitrifiable media at >−10° C. and almost complete avoidance of chilling injury at −20 to −25° C. and that allow slow warming after vitrification without freezing.

摘要： Methods and compositions are provided for the introduction and washout of vitrifiable concentrations of cryoprotectant in organs and tissues. The methods comprise cooling the organ to below −10° C. by perfusion with a solution having a freezing point below −10° C., a temperature from −10 to −40° C., and a tonicity from 1.1 to 2.0 times isotonic, after previous perfusion with said solution for a time insufficient for approximate osmotic equilibration of the organ with the solution. The methods further comprise increasing the concentration of cryoprotectant further at a temperature from −10 to −40° C. to prepare the organ or tissue for vitrification. The methods further comprise cooling and vitrifying the organ, rewarming it, and perfusing the organ with a vitrifiable concentration of cryoprotectant that is the same as or less than the concentration used for vitrification, without the addition of an osmotic buffering agent. Rewarming is accomplished either by rapid (>1°C./min, and preferably −0.2-20° C./min) elevation of arterial perfusate temperature from below −20° C. to above −15° C. during continuous perfusion of the organ or by perfusing the organ with pre-warmed arterial perfusate at >−15° C. Extraordinarily effective multicomponent compositions are also provided for the process, particularly involving a vitrification solution whose warming rate after vitrification can be
