Used in biomedical research to measure parathyroid hormone (PTH) levels in mouse serum, plasma, or tissue samples. Enables study of calcium regulation, bone metabolism, and endocrine disorders in mouse models. Commonly applied in preclinical studies related to hyperparathyroidism, kidney disease, osteoporosis, and hormonal imbalances. Provides a sensitive and specific method for quantifying PTH concentrations to support drug development and physiological research.
