Used in plant biology research to quantify levels of gamma glutamate-cysteine synthase (γ-GCS), an enzyme critical in the biosynthesis of glutathione. The ELISA kit enables precise measurement of γ-GCS protein concentration in plant tissue extracts, supporting studies on oxidative stress responses, antioxidant production, and plant defense mechanisms. Widely applied in agricultural research and environmental stress studies to evaluate plant health and resilience under abiotic stresses such as heavy metals, drought, and salinity. Provides a reliable tool for monitoring changes in enzyme levels during developmental stages or in response to external stimuli.
