Request InfoPromega Corp.Promega Corp. has launched the ROS-Glo H2O2, a nonhorseradish peroxidase (HRP)-dependent, plate-based bioluminescent assay designed to detect reactive oxygen species (ROS). It measures the activity of enzymes that generate or eliminate H2O2 and enables small-molecule screening, including low false hit rate, signal stability and compatibility with liquid handling. The homogeneous assay does not rely on a reaction catalyzed by HRP, which causes a high number of false hits. It also can be used to measure changes in the level of ROS by directly detecting H2O2 in cultured mammalian...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics May/Jun 2023 IssueTunable Laser SystemThe Tunable Laser System from Spectrolight Inc. is an all-in-one tunable light source system that enables precise selection of a broad spectral range from 410 to 1650 nm and easy bandwidth adjustment...BioPhotonics Sep/Oct 2023 IssueUpright MicroscopeThe ECLIPSE Ui integrated microscope-based viewing system from Nikon Instruments Inc. is designed for clinical and pathological observation.
