Used for the quantitative measurement of FAS (Fatty Acid Synthase) enzyme activity in mouse tissue extracts and biological samples. This ELISA kit enables researchers to assess FAS levels in studies related to lipid metabolism, obesity, diabetes, and cancer. It is particularly useful in preclinical research involving mouse models where changes in fatty acid synthesis are monitored in response to drugs, diet, or genetic modifications. The assay provides a sensitive and specific way to detect active FAS protein, allowing for high-throughput analysis in microplate format.
