Used to measure oxidized glutathione (GSSG) levels in biological samples such as tissue homogenates, plasma, and cell lysates. Helps assess oxidative stress in research models involving neurodegenerative diseases, aging, liver damage, and inflammatory conditions. Enables quantification of the GSSG-to-GSH ratio, a key indicator of cellular redox status. Suitable for studies in pharmacology, toxicology, and metabolic research where oxidative balance is critical. Provides a reliable, high-throughput method for evaluating antioxidant responses and the impact of experimental treatments on oxidative damage in rat models.
