Used in biomedical research to quantify levels of Parathyroid Hormone-related Protein (PTHrP) in biological samples such as serum, plasma, and cell culture supernatants. Enables investigation of PTHrP's role in calcium regulation, bone metabolism, and cancer-related hypercalcemia. Widely applied in studies of malignancies including breast, lung, and prostate cancers where PTHrP is overexpressed. Supports research into fetal development, cartilage biology, and smooth muscle regulation. Provides a sensitive and specific tool for monitoring disease progression and evaluating therapeutic interventions in experimental models.
