Used to measure sulfotransferase (SULT) enzyme activity in plant samples, this ELISA kit helps researchers study plant metabolism, particularly the sulfonation of hormones, flavonoids, and xenobiotics. It is widely applied in plant physiology and biochemistry research to understand how plants regulate growth, respond to environmental stress, and detoxify foreign compounds. The kit enables high-throughput analysis, making it valuable in agricultural science and environmental toxicology studies.
