Used for the detection and quantification of phytoene synthase (PSY) enzyme activity in plant samples, this ELISA kit supports research in plant biochemistry and metabolic engineering. It enables scientists to study carotenoid biosynthesis pathways, which are critical for plant pigmentation, photosynthesis, and antioxidant production. The kit is widely applied in agricultural research to evaluate genetically modified crops with enhanced nutritional value, such as biofortified rice or fruits with increased provitamin A content. It also aids in stress response studies, as PSY activity can be influenced by environmental factors like light, temperature, and oxidative stress. The assay is suitable for high-throughput analysis in plant breeding and functional genomics.
