Used in biomedical research to quantify levels of tryptophan hydroxylase 1 (TPH1) in rat samples, this ELISA kit enables accurate measurement of TPH1 concentration in tissue homogenates and biological fluids. It is widely applied in neuroscience and immunology studies to investigate serotonin synthesis pathways, as TPH1 is the rate-limiting enzyme in peripheral serotonin production. Researchers use this kit to assess changes in TPH1 expression in response to drugs, stress, inflammation, or genetic modifications. Its high sensitivity and specificity make it suitable for studying disorders linked to serotonin dysregulation, such as gastrointestinal diseases, mood disorders, and autoimmune conditions in rat models. The assay supports high-throughput screening and provides reliable data for preclinical research.
