Chromatography refrigerator and freezers for plant molecular biology

现代分子生物学和生物化学实验室需要专门的制冷和冷冻能力，以便安全有效地运行。 特别重要的是研究材料的长期储存，这些材料往往是多年工作的结果，通常是不可替代的。 此外，许多实验需要使用冷却到室温以下的专用设备进行，以产生准确，可重复的研究结果。 目前的应用是为萨斯喀彻温大学的新教员Christopher托德博士的实验室配备色谱冰箱、低温和超低温冷冻机，用于他的NSERC赞助的研究项目。托德博士的研究项目在分子和生物化学水平上研究了豆科植物氮代谢和固氮的调节。 豆科植物固氮是全球氮循环中极其重要的自然机制，因为它将蛋白质和其他生物分子的基本成分氮转化为植物可用的形式。 反过来，在农业豆类中，这为人类和牲畜的饮食提供了一种重要的氮供应方式。 目前的应用是支持托德博士的研究，以了解这些过程是如何在植物中调节，以及如何非生物胁迫，如水分限制，可能会影响这种调节。

A modern molecular biology and biochemistry laboratory requires specialized refrigeration and freezer capacity in order to operate safely and effectively.  Of particular importance is long-term storage of research material, often the result of years of work and usually irreplaceable.  In addition, many experiments need to be carried out with specialized equipment cooled below room temperature in order to generate accurate, reproducible research results.  The current application is to equip the lab of Dr. Christopher Todd, a new faculty member at the University of Saskatchewan, with a chromatography refrigerator, low temperature and ultra-low temperature freezers for use in his NSERC sponsored research program. Dr. Todd's research program examines the regulation of nitrogen metabolism and nitrogen fixation in legume species at the molecular and biochemical levels.  Nitrogen fixation in legumes is an extremely important natural mechanism in the global nitrogen cycle since it converts nitrogen, a fundamental component of protein and other biomolecules, to a form usable by the plants.  In turn, in agricultural legumes, this provides an important way to provide nitrogen to the diets of both humans and livestock.  The current application is to support Dr. Todd's research into understanding how these processes are regulated in plants and how abiotic stresses, such as water limitation, might affect this regulation.
