Description

Pth (13-34) (Human) is a synthetic peptide fragment corresponding to amino acids 13-34 of the human parathyroid hormone. This high-purity peptide is a critical research tool for studying calcium metabolism, bone biology, and endocrine signaling pathways. It is essential for researchers and developers in the pharmaceutical, biotechnology, and life science sectors, particularly for assay development, receptor binding studies, and as a reference standard.

Application

• Biomedical Research: Used as a key reagent in studies of parathyroid hormone (PTH) receptor interaction, signal transduction, and structure-activity relationships (SAR).
• Assay Development & Validation: Serves as a precise reference standard and calibrator in immunoassays (ELISA, RIA) and bioassays for PTH detection and quantification.
• Pharmaceutical R&D: Employed in the screening and development of novel therapeutics targeting bone disorders such as osteoporosis and hyperparathyroidism.
• Academic Research: A fundamental tool for investigating the physiological and pathological roles of PTH in calcium and phosphate homeostasis.
• Quality Control: Utilized as an in-house control material to ensure the accuracy and consistency of research and diagnostic methods involving PTH.
