Conventional Cryoprotectants
Conventional cryoprotectants are glycols (alcohols containing at least two hydroxyl groups), such as ethylene glycol, propylene glycol, and glycerol. Ethylene glycol is commonly used as automobile antifreeze, and propylene glycol has been used to reduce ice formation in ice cream. Dimethyl sulfoxide (DMSO) is also regarded as a conventional cryoprotectant. Glycerol and DMSO have been used for decades by cryobiologists to reduce ice formation in sperm and embryos that are cold-preserved in liquid nitrogen.

Famous quotes containing the word conventional:
“If the Nazis have really been guilty of the unspeakable crimes circumstantially imputed to them, then—let us make no mistake—pacifism is faced with a situation with which it cannot cope. The conventional pacifist conception of a reasonable or generous peace is irrelevant to this reality.”
—John Middleton Murry (1889–1957)
