Used in biochemical and medical research to measure the activity and concentration of catechol-O-methyltransferase (COMT) enzyme in plant samples. This kit enables researchers to study enzyme expression under various physiological conditions, stress responses, or genetic modifications. It is particularly useful in plant physiology studies, phytochemistry, and research related to secondary metabolite production, such as catecholamines and phenolic compounds. The assay supports high-throughput analysis and provides a reliable method for quantifying COMT in experimental plant models, contributing to understanding metabolic pathways and enzyme regulation in plants.
