Jäädytysprosessi
Jäädytysprosessi is a Finnish term that translates to "freezing process" or "cryopreservation" in English. It refers to the method of preserving biological material, such as cells, tissues, or even whole organisms, by cooling them to very low temperatures, typically below -130 degrees Celsius. At these temperatures, metabolic activity effectively stops, preventing degradation and maintaining the viability of the preserved material for extended periods.
The process usually involves a cryoprotective agent (CPA), a substance that protects the biological material from
The cooling rate is a critical factor in successful cryopreservation. Rapid cooling can lead to thermal shock
Upon thawing, the biological material needs to be warmed rapidly to prevent ice crystal growth during the
