Used in biomedical research to measure thyroxine (T4) hormone levels in mouse serum or plasma samples. Helps in studying thyroid function, endocrine disorders, and the impact of drugs or genetic modifications on the hypothalamic-pituitary-thyroid axis in mouse models. Widely applied in preclinical studies, toxicology assessments, and metabolic research where accurate quantification of thyroid hormones is essential. The ELISA format allows for high-throughput, sensitive, and specific detection, making it ideal for laboratory research settings.
