Application

Ammonia concentration was measured in serum and urine using the Sigma Ammonia Assay Kit in a study assessing expression of renal ammonia transporters in response to chromic metabolic acidosis.
This kit is for the quantitative, enzymatic determination of ammonia in food and biological samples. Ammonia reacts with α-ketoglutaric acid (KGA) and reduced nicotinamide adenine dinucleotide phosphate (NADPH) in the presence of L-glutamate dehydrogenase (GlDH) to form L-glutamate and oxidized nicotinamide adenine dinucleotide phosphate (NADP+). The decrease in absorbance at 340 nm, due to the oxidation of NADPH, is proportional to the ammonia concentration. L-Glutamate dehydrogenase reacts specifically with ammonia. The Ammonia Assay Kit may be used to determine ammonia concentrations in the range of 0.2-15 μg/ml.

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. How can I assess the absorbance change of my reagent blank when using Product AA0100, Ammonia Assay Kit?

    Generally, an absorbance change of 0.050 or less indicates an acceptable range for the reagent blank. An absorbance change higher than this indicates possible contamination of the reagent (or glassware) with ammonia.

  4. Is there a control that can be used to assess the accuracy of Product AA0100, Ammonia Assay Kit?

    A convenient control for use with this kit is the Ammonia Standard Solution that is provided in the kit.

  5. Which samples should be deproteinized for use with Product AA0100, Ammonia Assay Kit?

    The basis for this kit was a Diagnostic procedure for the determination of Ammonia in human plasma, whose total protein concentration is approximately 63 to 83 mg/mL. Thus, any solution whose protein concentration is less than approximately 83 mg/mL should not require deproteinization.

  6. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page. You can contact any of our Customer Sales and Service offices to receive a quote.  USA customers:  1-800-325-3010 or view local office numbers.
