原厂资料:
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.
Features - Benefits
Direct Cell-Based Detection: 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. Simple and Fast Assay: The homogeneous assay is performed following a simple two-reagent-addition protocol that does not require sample manipulation. The assay can be completed in less than 2 hours after reagent addition. Non-HRP-Based Detection: The ROS-Glo™ H2O2 Substrate reacts directly with H2O2, obviating the need for horseradish peroxidase (HRP) as a coupling enzyme and thus eliminating false hits associated with HRP inhibition. Automation-Compatible Format: Easily scale from 96- to 384-well plate formats. Flexible Assay: The assay can be used to screen compounds in both cell-based and enzyme-based formats. Multiplex-Compatible System: Get more informative data per well and reduce cell culture expenses by multiplexing with a real-time cytotoxicity assay (CellTox™ Green Cytotoxicity Assay) in the same well or with a viability assay.
Applications
Measure changes in hydrogen peroxide levels directly in cell culture samples.
Measure the activity of enzymes that generate or eliminate H2O2.
Identify small molecule inhibitors or inducers that alter ROS levels either in cells in culture or in enzyme assays.
