Overview
For quantitative determination of ammonia/ammonium and evaluation of drug effects on their metabolism. The assay uses FL360/450nm for signal readout. Compatible sample input includes Biological (eg urine) and environ-mental samples. Typical stated assay timing is 15 min.
Key elements and design rationale
- Readout format: FL360/450nm supports plate-based signal acquisition and consistent comparison across matched samples.
- Sample compatibility: The stated sample scope includes Biological (eg urine) and environ-mental samples, which is useful when aligning matrix type with calibration and control design.
- Analytical range context: The supplied specifications include a stated detection limit of 12 µM for interpreting low-signal samples.
- Feature emphasis: Fast and sensitive. Linear detection range of 0.012 – 1 mM ammonia.
Additional feature notes highlight Convenient and high-throughput. Homogeneous “mix-incubate-measure” type assay. Can be readily automated on HTS liquid handling systems for processing thousands of samples per day. Available format information for this listing includes 200 Tests.
Biological background
This product is centered on measurement of ammonia within the matrices described for the assay. In practice, datasets from this type of format are typically interpreted by comparing relative signal, activity, or abundance across matched control and experimental groups rather than relying on a single value in isolation. Careful alignment of sample matrix, incubation window, and calibration strategy is important when comparing results across plates, operators, or study days.
More details
AMMONIA (NH 3 ) or its ion form ammonium (NH 4 + ) is an important source of nitrogen for living systems and is ubiquitously present in the nature. Simple, direct and automation-ready procedures for measuring NH 3 are very desirable. BioAssay Systems ammonia/ammonium assay is based on an improved o-phthalaldehyde method. This reagent reacts with ammonia/ ammonium and forms a fluorescent product. The fluorescence intensity (λex/em = 360/450nm) is proportional to the ammonia concentration in the sampl

Research relevance and current trends
- Plate-based quantification and side-by-side group comparison remain central use cases for this assay format.
- The product notes emphasize multi-sample throughput, making it relevant for screening-oriented and larger batch comparison studies.
- The description supports intervention-focused study designs in which researchers compare baseline and perturbed conditions.
Common research applications
- Quantify ammonia in biological (eg urine) by FL360/450 nm readout.
- Compare treatment or phenotype groups using matched biological (eg urine) handling.
- Monitor time-course or pre/post changes in biological (eg urine) across study conditions.
Interpretation is usually strongest when signal changes are assessed alongside matrix-matched controls, replicate agreement, and the assay's stated analytical window.
Notes for experimental interpretation
- Matrix composition, background signal, and sample handling can influence apparent response; compare like-with-like whenever possible.
- Use appropriate blanks, controls, and replicate wells to distinguish biological differences from plate, reagent, or handling variability.
