Used to measure chalcone synthase (CHS) enzyme activity in plant samples, this ELISA kit helps researchers study flavonoid biosynthesis pathways. It is widely applied in plant physiology and molecular biology to investigate how plants produce secondary metabolites involved in UV protection, pigmentation, and defense against pathogens. The kit enables high-throughput analysis, making it valuable for screening plant varieties, studying gene expression effects, and evaluating responses to environmental stresses such as light exposure or pathogen attack.
