Used in plant physiology and agricultural research to quantify demagnesium chlorophyllase (PPH) enzyme activity, this ELISA kit enables precise measurement of PPH levels during chlorophyll degradation processes. It is particularly valuable in studying leaf senescence, fruit ripening, and stress responses in plants. Researchers use it to evaluate how environmental factors like light, temperature, and pathogens affect chlorophyll breakdown. The kit supports high-throughput analysis in crop science, helping develop strategies to improve post-harvest quality and shelf life of produce. It is also applied in genetic studies to assess PPH expression in transgenic or mutant plant lines.
