Used in biomedical research to measure levels of fatty acid synthase (FAS) in rat tissue samples or biological fluids. This kit enables researchers to quantify FAS protein expression, which is important in studying metabolic disorders, obesity, diabetes, and liver diseases. It is commonly applied in studies related to lipid metabolism, insulin resistance, and energy homeostasis in rodent models. The assay supports high-throughput analysis in preclinical research and helps evaluate the impact of drugs, diets, or genetic modifications on fatty acid synthesis pathways.
