Cryoprotectant

A cryoprotectant is a substance used to protect biological tissue or cells from damage caused by freezing. When water inside cells turns to ice, it can cause structural harm. Cryoprotectants work by reducing ice formation, lowering the freezing point, and preventing ice crystals from damaging the cells' membranes and structures. They help preserve the integrity and viability of biological samples during freezing and thawing, making it possible to store cells, tissues, or even entire organisms for future use. Common cryoprotectants include glycerol and DMSO.
