Cryopreservation: An Overview of Principles and Cell-Specific ...
WEBMar 24, 2021 · Principles of Cryopreservation. In order to fully understand the role of cryoprotective agents (CPAs), we must first understand the effects of subzero temperatures on otherwise healthy tissue. Exposing cells to temperatures below 0ºC without the aid of cryoprotectants is typically lethal.
