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