LI-COR Biosciences designs, manufactures, and markets instruments for biological and environmental research. It is ISO 9001 certified, meaning that it demonstrates "its ability to consistently provide products (which include services) that enhance customer satisfaction and meet applicable statutory and regulatory requirements."
Origins and history
LI-COR Biosciences is a privately held company based in Lincoln, Nebraska with subsidiaries in Germany and the United Kingdom. It was founded in 1971 under the name Lambda Instruments Corporation. The name was shortened to LI-COR, Inc. in 1978.
Products and Applications
LI-COR biotechnology instruments and reagents, which are based on near-infrared fluorescent and chemiluminescent detection, are used in a large variety of assays, such as western blot assays and cell-based assays, as well as in vivo imaging and DNA analysis. Primary applications include cancer research, drug discovery, genomics research, neuroscience, cell biology, and education.
LI-COR environmental instruments are used for photosynthesis research, greenhouse gas monitoring, greenhouse gas flux measurements, and soil respiration measurements. LI-COR also manufactures light sensors, leaf area meters, and plant canopy analyzers, all of which are used to make fundamental measurements in disciplines including plant physiology, climate change, agronomy (forestry and agriculture), and other areas of the natural sciences.
Scientific contributions and recognition
Researchers affiliated with micrometeorological networks around the world use LI-COR carbon dioxide and water vapor analyzers to assess ecosystem greenhouse gas exchange with the eddy covariance technique. These networks include FluxNet and regional networks such as AmeriFlux, ICOS, AsiaFlux, and others.
In 2013, the historic benchmark of increase in CO2 concentrations at 400 ppm was reported by the National Oceanic and Atmospheric Administration using LI-7000 Closed Path CO2/H2O gas analyzer.
