An assay is an investigative procedure in laboratory medicine, pharmacology, environmental biology, and molecular biology for qualitatively assessing or quantitatively measuring the presence or functional activity of the analyte, or the entity being targeted by the assay. Generally, assays involve biological materials or phenomena which tend to be intrinsically more complex in composition or in behavior than what can be handled by traditional chemical analysis and titration.

Peroxide assay kit, PEROXsay™
Supplier: G-Biosciences
PEROXsay™ is a colorimetric quantitative peroxide assay that measures the oxidation of ferrous (Fe²⁺+) ions to ferric (Fe³⁺) ions. Peroxides react with a sugar alcohol converting it to a peroxyl radical that subsequently starts the oxidation of ferrous ions to ferric ions. The acidic pH of the assay allows the ferric (Fe³⁺) ion to complex with the colorimetric reagent, resulting in a change in absorbance that is proportional to the peroxide concentration.

ROS Detection assay kit
Supplier: OZ BIOSCIENCES
ROS Detection Assay Kit is a cell-based assay designed for measuring Reactive Oxygen Species (ROS) activity within a cell using the cell-permeable fluorogenic probe 2', 7'-Dichlorodihydrofluorescein diacetate (DCF-DA). Once DCF-DA has diffused into cells it is deacetylated by cellular esterases to a non-fluorescent compound and rapidly oxidised by ROS into DCF. DCF is highly fluorescent and can be detected by microscopy, titration in microplate and also cytometry (ex 485/em 535). The fluorescence intensity that results is proportional to the ROS levels within the cell.
