Glutathione (GSH) is a tri-peptide (Glutamic acid, Cystein and Glycine) present in cells, showing an antioxidant effect allowing the reduction and the removal of Reactive Oxygen Species (ROS) and Peroxide from the cell. The new QuicGSHS3.0 probe from Goryo Chemicals will allow you to easily quantify intracellular concentration of GSH by Fluorescent Live cell Imaging.
