Abstract
Since its outgrowth from studies on freezing vinegar eels and spermatozoa over 25 years ago, cryopreservation of human red blood cells (RBC) has progressed considerably. The labors of transfusionists, physical chemists and bioengineers have brought forth increasingly sophisticated technology and equipment designed to minimize low-temperature RBC damage and maximize recovery after thawing. Careful evaluation of the viability and oxygen transport capabilities of thawed processed RBC indicate that the great majority of RBC recovered after suspended animation at -80°C for up to 10 years perform as well as fresh cells1: science fiction come true!A large proportion of donor plasma, . . .
