Used in plant biology research to measure glutathione peroxidase enzyme activity, this kit helps assess plant oxidative stress responses. It enables researchers to evaluate how plants defend against reactive oxygen species under environmental stresses such as drought, salinity, extreme temperatures, or pollution. By quantifying GSH-PX levels, scientists can study antioxidant mechanisms in crops and model plants, supporting work in improving stress tolerance, enhancing crop yield, and developing resilient plant varieties. The assay is commonly applied in agricultural research, environmental monitoring, and plant physiology studies.
