Used in life science research to quantify mouse thyroid-stimulating hormone (TSH) levels in serum or plasma samples. Enables researchers to study thyroid function and regulation in mouse models, particularly in endocrine disorders, autoimmune thyroid diseases, and hormone-related metabolic studies. Commonly applied in preclinical studies, toxicology assessments, and evaluation of drug effects on the hypothalamic-pituitary-thyroid axis. Provides high sensitivity and specificity for accurate measurement of TSH concentrations in small sample volumes.
