Used for the quantitative measurement of tyrosine hydroxylase (TH) activity in plant samples, this ELISA kit enables researchers to assess enzyme activity involved in the biosynthesis of important phenolic compounds and neurotransmitters in plants. It is widely applied in plant physiology and biochemistry studies to investigate stress responses, metabolic pathways, and signaling mechanisms. The kit supports high-throughput analysis, making it suitable for screening plant varieties or treatments that influence TH activity, such as environmental stressors or genetic modifications. Results are typically used in research related to plant defense mechanisms, secondary metabolism, and adaptation processes.
