Yes, you are always walking a tightrope between perfusate toxicity (which is temperature dependent) and the prevention of freezing (ice formation). Sophisticated computer-controlled perfusion technology has been developed for introducing and removing perfusate according to a precise temperature/time schedule. It appears to be working well enough to allow recovery of whole kidneys from -40'C, as Mike as described. ---Brian Wowk Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=5380
