Nowadays medicine and the biological sciences would be nothing without cryogenic technologies – what is known among specialists as the freezing of cellular and genetic material. Such specimens are then preserved in cryobanks – low-temperature refrigerators which maintain these chilly temperatures with the help of liquid nitrogen. A cryobank is not merely a negative 200-degree refrigerator – it is an advanced piece of equipment developed with the help of complex high technologies. There are only about 200 of them in the whole world and one of them is in the Russian city of Tyumen. There the cryobank is used not only to store biomaterial, but as the basis for scientific research in the field of biotechnology – and scientists in Tyumen have already succeeded in making significant discoveries.
