Used in plant stress physiology research to quantify dehydroascorbate reductase (DHAR) enzyme levels, this ELISA kit enables accurate measurement of DHAR activity in plant tissue extracts. It is particularly valuable in studies related to oxidative stress responses, as DHAR plays a key role in maintaining ascorbate redox balance, which protects plants from reactive oxygen species. Researchers use this kit to evaluate plant health under abiotic stresses such as drought, salinity, extreme temperatures, and heavy metal exposure. It supports work in agriculture, environmental science, and genetic engineering by providing a reliable tool to assess antioxidant defense mechanisms in crops and model plants.
