Urea Assays

Urea Assays

At Assay Genie we've developed a range of Urea assays for researchers to analyse key steps in the Urea Pathway.


Standard Curve in 96-well plate assay

Unique Urea Assay Kit!

Our popular Urea Assay Kit has been cited in several publications due to its unique advantages.

Key Advantages

  • Sensitive and accurate: Use 5 µL samples. Linear detection range 0.08 mg/dL (13 µM) to 100 mg/dL (17mM) urea in 96-well plate assay.
  • Simple and high-throughput: The procedure involves addition of a single working reagent and incubation for 20 min. Can be readily automated as a high-throughput assay for thousands of samples per day.
  • Minimum interference in biological samples: No interference with ammonia. No pretreatments are needed. Assays can be directly performed on raw biological
  • Flexible: Validated in a range of sample types (serum, plasma, urine, milk, cell/tissue culture, bronchoalveolar lavage (BAL), food, beverage, and environmental samples).
  • Stable and Versatile.
