The ROS-Glo™ H₂O₂ Assay is a homogeneous, fast and sensitive bioluminescent assay that measures the level of hydrogen peroxide (H₂O₂), a reactive oxygen species (ROS), directly in cell culture or in defined enzyme reactions. A derivatized luciferin substrate is incubated with sample and reacts directly with H₂O₂ to generate a luciferin precursor. Addition of ROS-Glo™ Detection Solution converts the precursor to luciferin and provides Ultra-Glo™ Recombinant Luciferase to produce light signal that is proportional to the level of H₂O₂ present in the sample.

ROS-Glo™ H₂O₂ Assay Chemistry

11359MA-W

The H₂O₂ Substrate reacts directly with H₂O₂ to create the Luciferin Precursor. The ROS-Glo™ Substrate Detection Solution converts the Luciferin Precursor to luciferin and also provides the Ultra-Glo™ Luciferase to produce light. Light signal is proportional to the amount of H₂O₂ in the sample well.

Overview of the ROS-Glo™ H₂O₂ Assay Protocol for Cell-Based or Biochemical Detection

11360MA-W

The assay follows a simple two-reagent-addition protocol that does not require sample manipulation. The ROS-Glo™ H₂O₂ Substrate can be added to assay wells with the treatment or at the end of the treatment incubation period, and data can be recorded in less than 2 hours after reagent addition.

ROS Induction in Cultured Cells

11901MA-W

Menadione treatment of K562 cells resulted in a concentration-dependent ROS increase as detected with the ROS-Glo™ H₂O₂ Assay. The assay can be performed in various cell culture media with or without serum, eliminating the need to remove the media from cultured cells before performing the assay.

NADH Oxidase Enzymatic Activity

11902MA-W

NADH Oxidase enzymatic activity was determined by incubating increasing concentrations of NADH oxidase with NADH in enzyme reaction buffer and measuring the H₂O₂ produced with the ROS-Glo™ H₂O₂ Assay. After appropriate levels of NADH oxidase and NADH substrate were determined, the assay was used to identify inhibitors of the enzyme in a chemical library by looking for decreased luminescence.

Multiplex With a Cytotoxicity Assay for More Informative Data Per Well 

11586MA-W

HepG2 cells were treated with either ROS-generating compounds (menadione or pyrogallol) or a cytotoxicity inducing reagent (digitonin) and incubated at 37°C for 2 hours. CellTox™ Green Dye (membrane impermeable DNA binding dye as an indicator of cytotoxicity) and H₂O₂ Substrate were added at the time of dosing. After incubation fluorescence from the CellTox™ Green Dye was measured followed by addition of ROS-Glo™ Detection Solution. Luminescence signal from the ROS-Glo™ Assay was measured following 20‑minute incubation.
