Used in plant biology research to quantify flavonol synthetase (FLS) enzyme levels, this ELISA kit enables accurate measurement of FLS concentration in plant tissue extracts. It supports studies on flavonoid biosynthesis pathways, helping researchers understand how plants produce flavonols—key compounds involved in UV protection, pigmentation, and defense mechanisms. The assay is widely applied in physiological and genetic studies of crops and model plants, aiding in the development of varieties with enhanced stress tolerance or improved nutritional content. The kit is also useful in screening transgenic plants where flavonol production has been modified through genetic engineering.
