Used for the detection and quantification of 3GT (3-O-glycosyltransferase) enzyme activity in plant samples, this ELISA kit enables researchers to study flavonoid biosynthesis pathways. It is particularly useful in plant physiology and genetic engineering to assess enzyme function in pigment production, such as anthocyanin formation, which affects flower and fruit color. The kit supports high-throughput screening in breeding programs and functional genomics to identify plant varieties with enhanced color traits or improved stress resistance linked to flavonoid metabolism.
