Krüokaitseainetega

Krüokaitseainetega, often referred to as cryoprotectants in English, are substances that help protect biological tissues from freezing damage. When water freezes, it forms ice crystals that can puncture cell membranes and disrupt cellular structures. Krüokaitseainetega work by reducing the formation of ice crystals or by preventing them from causing damage.

These compounds can be categorized into two main types: permeating and non-permeating. Permeating cryoprotectants, such as glycerol and dimethyl sulfoxide (DMSO), can enter cells and lower the freezing point of intracellular water. Non-permeating cryoprotectants, like sugars and polymers, remain outside the cells and help to stabilize cell membranes and reduce dehydration during the freezing process.

The effectiveness of a krüokaitseaine depends on its concentration, the rate of cooling, and the specific biological material being preserved. They are widely used in various fields, including cryopreservation of cells, tissues, and organs for research, medicine, and biotechnology. The goal is to maintain cell viability and functionality after thawing. Careful selection and application of krüokaitseainetega are crucial to minimize toxicity and maximize the success of cryopreservation.
