Used in biomedical research to quantify levels of flavin monooxygenase 3 (FMO3) in mouse samples, this ELISA kit enables accurate measurement of FMO3 protein expression in tissues such as liver and kidney. It is commonly applied in studies related to drug metabolism, detoxification pathways, and trimethylaminuria (TMAU) models, where FMO3 activity plays a critical role in oxidizing nitrogen- and sulfur-containing compounds. Researchers use this kit to assess changes in FMO3 levels under various experimental conditions, including drug treatments, genetic modifications, or metabolic diseases, supporting investigations into liver function, gut microbiome interactions, and xenobiotic processing. The assay provides high specificity and sensitivity, making it suitable for high-throughput screening and mechanistic studies in preclinical models.
