Enzo Life Sciences’ ROS-ID ROS/RNS detection kit is designed to directly monitor real time reactive oxygen and/or nitrogen species (ROS/RNS) production in live cells using fluorescence microscopy. The kit includes three fluorescent dye reagents: NO Detection Reagent (red fluorescent), Oxidative Stress Detection Reagent (green fluorescent) for total ROS detection, and Superoxide Detection Reagent (orange fluorescent). It also includes the positive controls, pyocyanin and L-arginine, which are common inducers of ROS and NO production, respectively, as well as the negative controls, N-acetyl-L-cysteine and c-PTIO (common scavengers of ROS and NO, respectively). Through the combination of the three detection probes with a set of specific inhibitors and activators, this kit enables discrimination among superoxide, nitric oxide and peroxynitrite. Applications: Fluorescence microscopy .
