Used in research settings to measure oxidized glutathione (GSSG) levels in plant samples, this ELISA kit enables scientists to assess oxidative stress and redox status in plant tissues. It is particularly useful in studies related to environmental stress responses, such as drought, salinity, heavy metal exposure, and pathogen attack. By quantifying GSSG, researchers can evaluate the antioxidant capacity of plants and understand how glutathione redox cycling contributes to cellular defense mechanisms. The kit supports high-throughput analysis and provides a sensitive and specific method for monitoring changes in the GSSG/GSH ratio, an important indicator of cellular oxidative damage and stress adaptation in plant physiology and molecular biology research.
