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 behaviour 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.
