Used to measure the activity of plant γ-glutamylcysteine synthetase (γ-GCS) in plant tissue samples, this ELISA kit supports research in plant physiology and stress response. It enables scientists to quantify γ-GCS levels, a key enzyme in glutathione biosynthesis, which plays a critical role in antioxidant defense and heavy metal detoxification in plants. The kit is widely applied in studies related to abiotic stress tolerance, such as drought, salinity, and heavy metal exposure, helping assess plant health and develop stress-resistant crop varieties. Its high sensitivity and specificity make it suitable for use in agricultural research, environmental monitoring, and plant biotechnology.
