Used in plant physiology research to quantify zeaxanthin epoxidase (ZEP) enzyme levels, this ELISA kit enables scientists to study the xanthophyll cycle and photoprotection mechanisms in plants. It is particularly valuable in stress response studies, such as drought, high light intensity, or temperature extremes, where ZEP activity influences non-photochemical quenching and overall photosynthetic efficiency. Researchers use this kit to assess plant health, adaptability, and resilience in agricultural and environmental studies, supporting crop improvement and sustainable farming strategies. The assay is also applied in genetic studies to evaluate ZEP expression in transgenic or mutant plant lines.
