Blood Urea Nitrogen Enzymatic Kit for Determination of Urea in Serum

The MaxDiscovery™ Blood Urea Nitrogen Enzymatic Kit is a microplate-based colorimetric assay for the determination of urea in serum samples produced from blood. Blood urea nitrogen (BUN) is an important marker for normal kidney and liver function. Elevation of BUN levels is often an indication of intestinal and kidney obstruction and cardiac failure. Decreased BUN levels are often associated with kidney and liver damage. BUN is also a very useful tool for preclinical investigation of experimental drug formulations and BUN levels are commonly used to monitor and attenuate the toxic effects of experimental drug formulations in rodents.

MaxDiscovery Blood Urea Nitrogen Enzymatic Kit uses an enzyme-based assay to determine urea in liquid samples such as serum. The test is based on a highly proven method for urea determination. The MaxDiscovery Blood Urea Nitrogen Enzymatic Kit contains sufficient
materials to test 42 samples in duplicate.

The assay utilizes urease, a metabolic enzyme, to specifically detect urea in serum. The MaxDiscovery Blood Urea Nitrogen Enzymatic Kit provides rapid, accurate, proven results even in complex liquid mixtures. The limit of detection for the test is 8 ppm urea for serum. The
linear range of the assay is 8 – 200 ppm analyte.
