Used in plant biochemistry research to quantify dihydroflavonol reductase (DFR) enzyme levels in plant tissues. This ELISA kit enables researchers to study flavonoid biosynthesis pathways, particularly in relation to pigment production, stress responses, and secondary metabolite regulation. It is commonly applied in studies of genetically modified plants, breeding programs, and physiological responses to environmental factors. The assay provides a sensitive and specific measurement of DFR protein concentration, supporting work in plant molecular biology and metabolic engineering.
