Overview
For quantitative determination of aconitase enzyme activity and high-throughput screening assays for aconitase modulator. The assay uses OD565nm for signal readout. Compatible sample input includes Biological samples (e.g. cell lysate, tissue homogenate, serum, etc.). Typical stated assay timing is 30 min.
Key elements and design rationale
- Readout format: OD565nm supports plate-based signal acquisition and consistent comparison across matched samples.
- Sample compatibility: The stated sample scope includes Biological samples (e.g. cell lysate, tissue homogenate, serum, etc.), which is useful when aligning matrix type with calibration and control design.
- Analytical range context: The supplied specifications include a stated detection limit of 0.5 U/L for interpreting low-signal samples.
- Feature emphasis: Fast and sensitive. Linear detection range (20 µL sample): 0.5 to 100 U/L for 20 min reaction.
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 100 Tests.
Biological background
This product is centered on measurement of aconitase 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
ACONITASE (ACONITATE HYDRATASE) is an enzyme in the citric acid (TCA) cycle that catalyzes the conversion of citrate to isocitrate. The activity of aconitase depends largely upon the iron-sulfur [Fe4S4]2+cluster. Related diseases include aconitase deficiency (e.g. myopathy and exercise intolerance), Friedreich’s ataxia, and diabetes. BioAssay Systems’ aconitase assay measures the isocitrate generated as a product of the aconitase reaction. The isocitrate is then oxidized producing NADPH and the oxidation product. The NADPH converts the dye to an intense violet color with an absorption maximum of 565 nm. The increase in absorbance at 565 nm is directly proportional to aconitase activity.
Detection method

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 aconitase in cell lysate, tissue homogenate, serum by OD565 nm readout.
- Compare treatment or phenotype groups using matched cell lysate, tissue homogenate, serum handling.
- Monitor time-course or pre/post changes in cell lysate, tissue homogenate, serum 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.
What time point do I use to calculate the isocitrate standard curve?
Use the OD565nm at 10 minutes to calculate the slope of the isocitrate standard curve.
