Re: cryogenics?

... (or cryoprotectants). With animal cells, you need to add something that prevents ice crystal formation, the most common ones being DMSO and glycerol. Also, some small invertebraters such as tardigrada (water bears) use the sugar trehalose to prevent ice crystal formation, and thus they can ...
