HIGH-FIDELITY LONG-TERM STORAGE OF BIOLOGICAL MATERIAL

摘要

The disclosure relates to the long-term preservation of biological material such as DNA, RNA, a stem cell, a tissue or an organ. The preservation container comprises a biological container (a), a first shield (b) configured for absorbing gamma-rays, and a second shield (c) configured for absorbing ambient neutrons, said second shield surrounding the biological container, wherein the preservation container is of low-radioactivity background materials. Preferably, the preservation container is a cryostat and further comprises a cryogenic container (h) containing a cold source (f). To better preserve the biological material, a method for preserving a biological material is disclosed, comprising providing the biological material in a confinement container, placing the confinement container into said preservation container, and storing the preservation container in a room located under a material attenuating cosmic rays and induced particles, said material having a thickness equivalent to 1 m to 7000 m of water.
