Used to measure dihydroflavonol 4-reductase (DFR) enzyme activity in plant tissues, this ELISA kit helps researchers study flavonoid biosynthesis pathways. It is widely applied in plant physiology and biochemistry to understand pigment formation, stress responses, and secondary metabolite production. The kit enables high-throughput analysis, making it valuable in agricultural research, plant breeding, and genetic engineering to develop plants with improved color traits or enhanced antioxidant capacity.
