Used in plant biology research to quantify levels of β-ketoacyl-ACP synthase I (KAS1), an essential enzyme in fatty acid biosynthesis. The ELISA kit enables precise measurement of KAS1 protein concentration in plant tissue extracts, supporting studies on lipid metabolism, plant development, and responses to environmental stress. It is particularly useful in genetic and metabolic engineering projects where modulation of fatty acid pathways is targeted, such as in the development of crops with improved oil content or altered fatty acid profiles. The assay is also applied in quality control during recombinant protein expression in plant-based expression systems.
