Preservative solution for cells, tissues and organs containing rare sugar and preservative method thereof
A preservative solution for low temperature preservation of animal or human organs and animal or plant tissues or cells contains D-allose. For the human kidney, cells derived from animals or humans, or human or animal sperm and/or ovum and/or fermented ovum, the preservation is conducted at from −5 to 20° C. For cells derived from animals or humans, or human or animal sperm and/or ovum and/or fermented ovum, the preservation is conducted at a temperature at which to start freezing to −196° C. A method for the low temperature preservation of an animal or human organ and an animal or plant tissue or cell at a low temperature comprises (a) refluxing or immersing a preservative solution containing D-allose and the organ or the tissue or mixing the cell therewith, and (b) cooling the organ, the tissue or the cell to a low temperature of from −5 to 20° C.
1. A preservative solution for low temperature preservation of animal or human organs and animal or plant tissues or cells, wherein the solution is a University of Wisconsin solution containing 0.4M to 0.6M of D-allose.
2. A method for low temperature preservation of an animal or human organ or an animal or plant tissue at a low temperature, which comprises (a) contacting the organ or the tissue with a preservative solution containing 0.4M to 0.6M of D-allose for low temperature preservation, and (b) cooling the organ or the tissue being contacted with the preservative solution to a low temperature of from −5 to 20° C.
3. The method according to claim 2 , which preserves a human kidney.
4. A method for low temperature preservation of a human or animal cell at a low temperature, which comprises (a) contacting the cell with a preservative solution containing 0.4M to 0.6M of D-allose for low temperature preservation, and (b) cooling the cell being contacted with the preservative solution to a low temperature of from −5 to 20° C.
