Description

Pth (1-31) (Human) CAS NO 157938-23-3 is a synthetic peptide fragment corresponding to amino acids 1-31 of the human parathyroid hormone. This high-purity peptide is a critical research tool for studying calcium metabolism, bone physiology, and endocrine signaling pathways. It is primarily utilized by pharmaceutical R&D teams, academic research institutions, and biotechnology companies focused on metabolic disorders and osteoporosis research.

Application

• Biomedical Research: Fundamental studies on the structure, function, and signaling mechanisms of parathyroid hormone (PTH).
• Drug Discovery & Development: Serving as a reference standard, antigen, or lead compound in the development of novel therapeutics for osteoporosis and hyperparathyroidism.
• In Vitro Assays: Used in cell-based assays and receptor binding studies to evaluate biological activity and screen for PTH receptor agonists or antagonists.
• Antibody Production: Acting as an immunogen for generating specific antibodies used in diagnostic immunoassays and immunohistochemistry.
• Metabolic Studies: Investigating the role of PTH in calcium and phosphate homeostasis in renal and bone tissue models.
