Cell tissue must not freeze!

Nature has evolved sugars, amino acids, and special antifreeze proteins as cryoprotectants. People use organic solvents and synthetic polymers as additives to prevent cell cultures from freezing damage. Now, English scientists have combined both methods: In work published in the journal Angewandte Chemie, they introduced polyproline, a polypeptide made of the natural amino acid proline, as an effective cryoprotectant for monolayers of cells. …read more
