Used in plant stress physiology research to quantify monodehydroascorbate reductase (MDHAR) enzyme levels, this ELISA kit enables assessment of antioxidant capacity in plant tissues under abiotic stress conditions such as drought, salinity, extreme temperatures, and heavy metal exposure. It supports studies on oxidative stress responses by measuring MDHAR activity in the ascorbate-glutathione cycle, helping researchers evaluate plant health and redox status. Commonly applied in agricultural science, environmental toxicology, and plant biotechnology to screen stress-tolerant crop varieties and investigate molecular mechanisms of reactive oxygen species (ROS) scavenging. Suitable for use with leaf extracts, root tissues, and cell cultures from a wide range of plant species.
