Product Description

The ab83362 Urea Assay Kit is a rapid, simple, sensitive and reliable assay used to quantify urea in a variety of samples such as serum, plasma and urine etc. It can be used as a blood urea nitrogen test kit (BUN test kit). In the urea assay protocol, enzymes act on urea to form a product that reacts with a probe to generate colour (ODmax=570nm). The absorbance is directly proportional to the concentration of urea in the solution. The kit can detect as little as 0.5 nmol per well or 10 µM of urea.

  • Urea Assay Protocol Summary:
  • add samples and standards to wells
  • add the reaction mixture and incubate for 60 min at 37ºC
  • analyze with a microplate reader


This product is manufactured by BioVision, an Abcam company and was formerly called the K375 Urea Colorimetric Assay Kit. K375-100 is the same size as the ab83362 test size 100.

Platform: microplate reader


Storage instructions

Store at -20°C. Consult the protocols.


Urea is a waste product that is produced in the liver, dissolved in the blood (at a concentration of 2.5 to 7.5 mM), and secreted by the kidneys. Urea also plays a very important role in protein catabolism, the removal of toxic ammonia from the body, and the countercurrent system that allows the reabsorption of water and critical ions in the nephrons.
