Used in plant research to quantify the activity of UDP-glucose flavonoid 3-O-glucosyltransferase (UFGT), an enzyme critical in the biosynthesis of anthocyanins—pigments responsible for red, purple, and blue colors in fruits and flowers. This ELISA kit enables researchers to monitor UFGT levels during fruit ripening, study color development in plants, and evaluate the impact of environmental or genetic factors on flavonoid pathways. It is widely applied in agricultural science, breeding programs, and quality control of horticultural crops to improve color traits and nutritional value.
