Used in biomedical research to quantify levels of tryptophan hydroxylase 1 (TPH1) in mouse samples. This ELISA kit enables researchers to measure TPH1 protein concentration in tissue homogenates, cell lysates, or biological fluids. TPH1 is the rate-limiting enzyme in serotonin synthesis outside the central nervous system, primarily in the gut and peripheral tissues. The kit supports studies on serotonin-related pathways, gastrointestinal disorders, immune regulation, and neuroendocrine function in mouse models. It is a valuable tool for preclinical research investigating mood, appetite, inflammation, and carcinoid tumors where peripheral serotonin plays a role. High sensitivity and specificity allow for accurate detection even in low-abundance samples, facilitating reliable data collection in experimental and therapeutic studies.
