Used in biomedical research to measure levels of parathyroid hormone-related protein (PTHrP) in rat samples, this ELISA kit enables the study of calcium regulation, bone metabolism, and tumor-induced hypercalcemia in preclinical models. It is widely applied in endocrinology, oncology, and pharmacology research to assess PTHrP secretion in cell cultures, serum, or tissue extracts. The assay supports investigation into diseases involving abnormal calcium homeostasis and helps evaluate therapeutic interventions targeting hormonal pathways in rodent models.
