Used in plant research to quantify dihydroflavonol 4-reductase (DFR) enzyme levels, this ELISA kit helps study flavonoid biosynthesis pathways. It is widely applied in plant physiology and genetics to analyze DFR expression in response to environmental stresses, developmental stages, or genetic modifications. Researchers use it to evaluate the regulation of anthocyanin and proanthocyanidin production, which are important for plant pigmentation, UV protection, and defense mechanisms. The kit supports high-throughput screening in breeding programs and functional genomics studies focused on improving crop quality and stress tolerance.
