Overview
For quantitative determination of glucose and evaluation of drug effects on glucose metabolism. The assay uses OD630nm (Chemical) for signal readout. Compatible sample input includes Biological, food, and beverage. Typical stated assay timing is 10 min.
Key elements and design rationale
- Readout format: OD630nm (Chemical) supports plate-based signal acquisition and consistent comparison across matched samples.
- Sample compatibility: The stated sample scope includes Biological, food, and beverage, which is useful when aligning matrix type with calibration and control design.
- Analytical range context: The supplied specifications include a stated detection limit of 0.7 mg/dL (39 µM) for interpreting low-signal samples.
- Feature emphasis: Sensitive and accurate. Use as little as 5 µL samples. Linear detection range from 0.7 mg/dL (39 µM) to 300 mg/dL (16.6 mM) glucose in a 96-well plate.
Additional feature notes highlight Simple and convenient. The procedure involves the addition of a single working reagent and incubation for 8 min in a boiling water bath; Improved reagent stability. The optimized formulation has greatly enhanced the reagent and signal stability. Available format information for this listing includes 100 Tests.
Biological background
This product is centered on measurement of glucose 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
Glucose (C6H12O6) is a ubiquitous fuel molecule in biology. It is oxidized through a series of enzyme-catalyzed reactions to form carbon dioxide and water, yielding the universal energy molecule ATP. Due to its importance in metabolism, glucose level is a key diagnostic parameter for many metabolic disorders. Increased glucose levels have been associated with diabetes mellitus, and hyperactivity of the thyroid, pituitary, and adrenal glands. Decreased levels are found in insulin-secreting tumors, myxedema, hypopituitarism, and hypoadrenalism. Simple, direct, and automation-ready procedures for measuring glucose concentrations find wide applications in research and drug discovery. BioAssay Systems glucose assay kit is designed to measure glucose directly in serum or plasma without any pretreatment. The improved o-toluidine method utilizes a specific color reaction with glucose. The absorbance at 630nm is directly proportional to glucose concentration in the sample.
Detection method
Colorimetric (OD 630 nm).
Detection limit and analytical sensitivity
Reported detection limit: 0.7 mg/dL (39 µM).
Procedures and timing
Stated procedure or timing information: 10 min.
Research relevance and current trends
- Plate-based quantification and side-by-side group comparison remain central use cases for this assay format.
- The description supports intervention-focused study designs in which researchers compare baseline and perturbed conditions.
- Short assay timing and plate compatibility support time-course or repeated-measure collection plans when handling is kept consistent.
Common research applications
- Quantify glucose in biological, food, and beverage by OD630 nm (Chemical) readout.
- Compare treatment or phenotype groups using matched biological, food, and beverage handling.
- Monitor time-course or pre/post changes in biological, food, and beverage 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 is the principle of the assay?
The QuantiChrom™ Glucose Assay is based on the formation of a blue-green complex between D-glucose and o-toluidine. The carbonyl group in the open aldehyde form of D-glucose condenses with the amino group of o-toluidine to form a stoichiometric colored imino adduct.
Does this assay measure fructose?
The reaction is specific to aldosugars (such as glucose) but not ketosugars (such as D-fructose). For instance in an equimolar solution of glucose and fructose, this method will measure only glucose.
What other sugars interfere with it?
Aldosugars would interfere in this assay, such as glyceraldehyde, ribose, arabinose, xylose, mannose, galactose. However, as glucose is the main sugar in biological samples (e.g. serum, cell culture medium), the interference is most often negligible.
Does phenol red in culture medium interfere with the glucose assay?
No, phenol red in the culture media does not interfere with this assay.
