CSBR: Natural History Collections: Liquid Nitrogen Facilities for Biological Specimen Curation and Research at the California Academy of Sciences

该项目将建立一个现代液氮储存系统，以确保长期保存加州科学院（CAS）的组织和基因收藏。这个为期一年的项目将购置和安装新的液氮冷冻器、缺氧安全监测器和干冰机。随后将组织和DNA标本从-80ºC的电冰箱转移到新系统中。液氮提供更冷的储存（-190ºc），降低了电冷冻机的成本和风险。该系统将为不可替代的生物资源提供高效、稳定、可靠的长期存储。中科院不断增长的组织和基因收藏支持着全球科学界。这些遗传资源已被用于许多研究，包括生物多样性研究、全球气候变化的影响、保护政策和管理研究以及基础科学研究。此外，拟议项目的每一步都将由中科院科学可视化团队记录，他们将为“科学在行动”展览制作视频。这段视频将在博物馆的公共楼层、网页和其他机构资源中使用，它将传达冷冻基因收藏的价值和重要性。

The project will establish a modern liquid nitrogen storage system to ensure the long-term preservation of the tissue and genetic collections housed at the California Academy of Sciences (CAS). This one-year project will acquire and install new liquid nitrogen freezers, an oxygen deficiency safety monitor, and a dry ice maker. This will be followed by the transfer of tissues and DNA collections from -80ºC electric freezers to the new system. Liquid nitrogen provides colder storage (-190ºc) and reduces costs and risks of electric freezers. This new system will provide efficient, stable, and reliable long-term storage for irreplaceable biological resources.The growing tissue and genetic collections at CAS support the global scientific community. These genetic resources have been used in numerous studies, including studies of biodiversity, the effects of global climate change, studies of conservation policy and management, as well as basic scientific research. In addition, every step of the proposed project will be documented by the CAS Science Visualization team, who will produce a video for the "Science in Action" exhibit. This video will be used in the museum public floor, web pages, and other institutional resources, and it will communicate the value and importance of frozen genetic collections.
