Used to measure the activity of Caffeic Acid O-Methyltransferase (COMT) in plant samples, this ELISA kit is essential in plant physiology and biochemistry research. It helps scientists study lignin biosynthesis, as COMT plays a key role in the pathway. Researchers use it to evaluate genetic modifications in plants, especially in crops engineered for reduced lignin content to improve biofuel production and forage digestibility. The kit is also applied in stress response studies, as COMT activity can change under environmental stresses like pathogen attack or UV exposure. Its high sensitivity allows detection of small changes in enzyme levels, making it valuable in screening plant varieties and understanding metabolic regulation in plant cell walls.
