Overview
For quantitative determination of αKG in serum, tissue and cell lysates. The assay uses OD570nm or FL530/585nm for signal readout. Compatible sample input includes Serum, tissue and cell lysate. Typical stated assay timing is 30 min.
Key elements and design rationale
- Readout format: OD570nm or FL530/585nm supports plate-based signal acquisition and consistent comparison across matched samples.
- Sample compatibility: The stated sample scope includes Serum, tissue and cell lysate, which is useful when aligning matrix type with calibration and control design.
- Analytical range context: The supplied specifications include a stated detection limit of 1.3 μM for OD, 0.08 μM for FL for interpreting low-signal samples.
- Feature emphasis: Sensitive and accurate. Linear detection range in 96-well plate: 1.3 to 200 μM for colorimetric assays and 0.08 to 20 μM for fluorimetric assays.
Additional feature notes highlight Fast and convenient. Room temperature assay with a 30 min incubation. No 37°C incubator is needed; High-throughput. Homogeneous “mix-incubate-measure” type assay. Can be readily automated to assay thousands of samples per day. Available format information for this listing includes 100 Tests in 96-well plate.
Biological background
This product is centered on measurement of α-ketoglutarate 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
α-Ketoglutarate (αKG)is a crucial intermediate in the citric acid (TCA) cycle and plays an important role in amino acid formation, nitrogen transport, and oxidation reactions. αKG can modulate muscle and bone growth as well as the aging process, and has also been investigated for its potential to enhance anticancer immune functions. BioAssay Systems’ α-ketoglutarate assay uses a single Working Reagent that combines αKG deamination, pyruvate oxidation and hydrogen peroxide determination. The change in OD570nm or fluorescence intensity at λex/em= 530/585nm is directly proportional to the αKG present in the sample.

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.
- Short assay timing and plate compatibility support time-course or repeated-measure collection plans when handling is kept consistent.
Common research applications
- Quantify α-ketoglutarate in serum, tissue and cell lysate by OD570 nm or FL530/585 nm readout.
- Compare treatment or phenotype groups using matched serum, tissue and cell lysate handling.
- Monitor time-course or pre/post changes in serum, tissue and cell lysate 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.
Can linear curve fitting be used?
While linear curve fitting can be applied in theory, we recommend using the internal standard method as described in the protocol. This approach accounts for sample matrix effects and improves accuracy and reproducibility, especially when working with complex biological samples.
Do urine samples work with this assay?
Urine samples are confirmed to be incompatible with this assay, possibly due to high salt and interfering metabolites in urine, including pyruvate.
When tissue is used, should it be freshly obtained? Or is -80°C storage ok?
If direct sample processing is not possible, we recommend snap freezing tissue samples in liquid nitrogen and keeping them either in liquid nitrogen or at -80°C until further processing.
