Abstract
A method of cryopreserving biological material by administering a cryoprotective agent mixture is provided. The mixture must be produced in a concentration sufficient to permit vitrification. The cryoprotective agent is an alkoxylated organic compound. The method includes administering the cryoprotective agent mixture and cooling the biological material until it is vitrified. Preferred cryoprotective mixtures contain 3 methoxy-1,2 propanediol and 2-methoxy ethanol.
