Cryopreservation or cryoconservation is a method wherever organelles, cells, tissues, living thing matrix, organs or the other biological constructs liable to injury caused by unregulated chemical dynamics square measure preserved by cooling to terribly low temperatures[1] (typically -80 °C exploitation solid dioxide or -196 °C exploitation liquid nitrogen). At low enough temperatures, any protein or chemical activity which could cause injury to the biological material in question is effectively stopped. Cryopreservation strategies request to succeed in low temperatures while not inflicting extra injury caused by the formation of ice throughout phase transition. ancient cryopreservation has relied on coating the fabric to be frozen with a category of molecules termed cryoprotectants. New strategies square measure perpetually being investigated because of the inherent toxicity of the many cryoprotectants.[2] By default cryopreservation alters or compromises the structure and performance of cells unless it's evidenced otherwise for a specific cell population. Cryoconservation of animal genetic resources is that the method during which animal genetic material is collected and keep with the intention of conservation of the breed.
