Used in plant stress physiology research to quantify proline dehydrogenase (PDH) enzyme levels, this ELISA kit enables scientists to assess plant responses to environmental stresses such as drought, salinity, and extreme temperatures. By measuring PDH concentration in plant tissue extracts, researchers can study proline metabolism regulation, which plays a key role in osmotic adjustment and cellular protection. The kit is widely applied in agricultural research and breeding programs aiming to develop stress-tolerant crop varieties. It supports high-throughput analysis in laboratories focusing on plant biochemistry, molecular biology, and functional genomics.
