Used in plant biology research to quantify β-ketoacyl-ACP synthase I (KASI) enzyme levels in plant tissues. This ELISA kit enables researchers to study fatty acid biosynthesis pathways, particularly in plastids, where KASI plays a key role in the elongation of fatty acid chains. It is widely applied in studies related to plant lipid metabolism, seed oil production, and genetic modification of crops for improved oil content or biofuel development. The assay supports high-throughput analysis, making it useful in both academic and agricultural research settings.
