Used for the quantitative measurement of Dehydroascorbate Reductase (DHAR) enzyme activity in plant tissue samples. This ELISA kit enables researchers to assess plant antioxidant capacity by measuring DHAR's role in the ascorbate-glutathione cycle. It is widely applied in plant physiology and stress response studies, such as under drought, salinity, or heavy metal exposure. The assay helps in evaluating plant health, oxidative stress tolerance, and the efficiency of antioxidant defense mechanisms in crops and model plants. Suitable for use in agricultural research, environmental stress studies, and genetic modification evaluations.
