Used in plant biology research to quantify chalcone isomerase (CHI) levels in plant tissue samples. This ELISA kit enables researchers to study flavonoid biosynthesis pathways, as CHI plays a key role in converting chalcone to flavanone, a critical step in producing pigments, phytoalexins, and signaling molecules. It is widely applied in studies related to plant stress responses, development, and secondary metabolism. The assay provides a sensitive and specific method for measuring CHI concentration in leaf extracts, cell cultures, or transgenic plants, supporting work in agriculture, biochemistry, and genetic engineering.
