Used for detecting and quantifying ZEP (zeaxanthin epoxidase) enzyme activity in plant samples, this ELISA kit enables researchers to study plant stress responses and photosynthetic regulation. It is particularly useful in plant physiology and agricultural research to assess how plants adapt to environmental stresses like drought, high light, or temperature extremes. By measuring ZEP activity, scientists can evaluate the efficiency of the xanthophyll cycle, which plays a key role in photoprotection. This kit supports high-throughput analysis in breeding programs and genetic studies aimed at developing stress-tolerant crop varieties.
