Description

Parathyroid Hormone (19-38) CAS NO 84057-87-4 is a bioactive synthetic peptide fragment corresponding to amino acids 19-38 of the native parathyroid hormone. This compound is a critical research tool for investigating calcium and phosphate metabolism, bone biology, and renal function. It is primarily utilized by pharmaceutical R&D teams, academic researchers, and diagnostic manufacturers focused on metabolic disorders and endocrine research.

Application

• Biomedical Research: Used as a reference standard and active agent in studies of PTH receptor binding, signal transduction, and the structure-activity relationship (SAR) of parathyroid hormone.
• Pharmaceutical Development: Serves as a key intermediate or reference compound in the development of novel therapeutics for osteoporosis, hyperparathyroidism, and hypoparathyroidism.
• Diagnostic Assays: Employed in the calibration and validation of immunoassays (e.g., ELISA) designed to measure PTH levels in clinical samples.
• Cell Biology Studies: Applied in in vitro cell culture models to study the effects of PTH on osteoblast and osteoclast activity.
• Biochemical Reagent: Functions as a high-purity biochemical reagent for enzymatic studies and protein interaction analysis.
