n. (plural of cryoprotectant English)
Usage examples of "cryoprotectants".
The first is getting the cryoprotectants, which tend to be very toxic in concentration, to every cell in the body without killing the body in the process.
The third and fourth problems are the reverse of the first two, thawing the subject safely, and getting all the cryoprotectants back out of the subject.
Once brought back to a temperature above freezing the subject needs to be deperfused to flush the cryoprotectants back out of the system, then finally warmed back up to body temperature, hopefully none the worse for the wear.
