Overview
For quantitative determination of D-sorbitol and evaluation of drug effects on sorbitol metabolism. The assay uses OD565nm for signal readout. Compatible sample input includes Biological (e.g. blood), food, beverage, and agriculture samples. 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 (e.g. blood), food, beverage, and agriculture 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 5 µM for interpreting low-signal samples.
- Feature emphasis: Fast and sensitive. Linear detection range (20 µL sample): 5 to 1000 µM D-sorbitol.
Additional feature notes highlight Convenient and high-throughput. Room temperature assay. No 37°C incubator is required. 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 sorbitol 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
SORBITOL (glucitol) is a sugar alcohol that is metabolized slowly in the human body. Sorbitol can be obtained from glucose by reducing the aldehyde group to a hydroxyl group. Accumulation of excessive sorbitol in erythrocytes, retinal cells, and Schwann cells has been associated with retinopathy, cataracts, peripheral neuropathy, and diabetes. Sorbitol is made solely from corn syrup, and found in fruits such as apples, pears, peaches, and prunes. It is widely used as a sugar substitute and as a laxative. It is also utilized in specialty culture media and in healthcare, food, and cosmetic products. Sorbitol is measured in biological samples to monitor metabolic pathways and the progression of diabetes. BioAssay Systems sorbitol assay involves an end-point enzyme coupled MTT/NAD reaction that forms a colored product with an absorption maximum of 565 nm. The increase in absorbance at 565 nm is directly proportional to the sorbitol concentration.

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 sorbitol in biological (blood) by OD565 nm readout.
- Compare treatment or phenotype groups using matched biological (blood) handling.
- Monitor time-course or pre/post changes in biological (blood) 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.
