Used in biomedical research to measure rat parathyroid hormone (PTH) levels in serum, plasma, or cell culture samples. This ELISA kit enables accurate quantification of PTH concentration, supporting studies on calcium metabolism, bone disorders, kidney function, and endocrine diseases in rodent models. It is widely applied in preclinical research, pharmacology, and toxicology to assess the impact of drugs or disease conditions on the parathyroid system. The assay is sensitive, specific, and suitable for high-throughput analysis in laboratory settings.
