Used in plant stress physiology research to quantify pyrroline-5-carboxylic acid synthase (P5CS) enzyme levels, this ELISA kit helps assess plant responses to abiotic stresses such as drought, salinity, and extreme temperatures. By measuring P5CS activity, researchers can evaluate proline biosynthesis, a key osmoprotectant pathway in plants, making it valuable for studies in crop improvement and stress tolerance. It is widely applied in agricultural research, plant biotechnology, and environmental stress studies to develop resilient plant varieties and understand molecular mechanisms underlying stress adaptation.
