Chromatography refrigerator and freezers for plant molecular biology

点击翻译按钮获取中文摘要

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.
