Used in biomedical research to quantify levels of tryptophan hydroxylase (TPH) in mouse samples, this ELISA kit enables accurate measurement of TPH concentration in tissue homogenates, serum, or cell lysates. It is particularly valuable in neuroscience and immunology studies where serotonin synthesis pathways are investigated, as TPH is the rate-limiting enzyme in serotonin production. Researchers use this kit to assess changes in TPH expression in response to drugs, behavioral models, or disease states such as depression, anxiety, or gastrointestinal disorders in mouse models. The assay supports high-throughput analysis with high sensitivity and specificity, making it ideal for preclinical studies exploring the serotonergic system.
