A. n. A cryoprotective agent.
1968Jrnl. Protozool. XV. 723/2 The best cryoprotectants were ethylene glycol, glycerol, and DMSO. 1982High Technol. Jan.–Feb. 85/1 Researchers..study ways to prevent freeze-thaw damage by using chemical cryoprotectants that pre-condition seeds prior to freezing by cold-hardening. 1984Holtzman & Novikoff Cells & Organelles (ed. 3) iii. xi. 470 Cells can be stored, apparently indefinitely, in liquid nitrogen at -196°C. When frozen carefully, in order to limit the formation of ice crystals (sometimes ‘cryoprotectants’ such as glycerol or dimethylsulfoxide (DMSO) are added), and then carefully thawed, cells..will resume growth and division. 1994Interzone July 44/3 Even with the use of glycol as a cryoprotectant, White will suffer freezing damage which must be repaired before he can live.
B. adj.= *cryoprotective a.
1969Surg., Gynecol. & Obstetr. CCXXVIII. 571 (heading) Effects of cryoprotectant compounds on mammalian heart muscle. 1972Sci. News 19 Aug. 125 Offerijns has actually frozen them [sc. the ‘pacemaker’ cells of the heart], using a cryoprotectant agent called dimethyl sulfoxide (DMSO), and revived 80 percent of them successfully. 1986Cryo-Lett. VII. 355 The cryoprotectant solution utilized in this study was Dimethyl Sulphoxide. |
