Used for the quantitative measurement of glutathione S-transferase (GST) enzyme activity in plant samples. This ELISA kit enables researchers to assess plant stress responses, as GST plays a key role in detoxification processes. It is widely applied in plant physiology and environmental studies to evaluate the impact of pollutants, herbicides, or oxidative stress on plant health. The assay is suitable for high-throughput analysis in agricultural research and phytoremediation studies.
