Latest Cryoprotectant Stories
Scientists have made an important step forward in their understanding of cryoprotectants â€“ compounds that act as natural 'antifreeze' to protect drugs, food and tissues stored at sub-zero temperatures.
Cryoprotectants needed to preserve eggs for reproduction need to be given in stages, albeit rapid ones, say scientists who have developed a mathematical model that predicts optimal time for loading and unloading these drugs.
