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.

The ActivX® FP serine hydrolase probes enable selective labeling and enrichment of active serine hydrolases. Fluorophosphonate (FP) probes specifically label serines of enzymatically active serine hydrolases. FP probes are also effective for screening small molecule inhibitors against enzymes derived from cell lysates, subcellular fractions, tissues and recombinant proteins. Depending on the active-site probe tag group and the enzyme class to be profiled, active site-labeled enzymes are detected and quantified by Western blot, fluorescent gel imaging or mass spectrometry.
