Description

Calcitonin (Salmon), 22-De-L-Tyrosine- (9Ci) is a synthetic analog of the natural peptide hormone calcitonin, designed for enhanced stability and research utility. This compound is critical for studying calcium metabolism, bone physiology, and related endocrine pathways. It is primarily utilized by pharmaceutical R&D teams, academic research institutions, and biotechnology companies engaged in metabolic disorder and osteoporosis research.

Application

• Pharmaceutical Research & Development: As a reference standard and active ingredient in preclinical studies for osteoporosis and hypercalcemia treatments.
• Biochemical Assay Development: Used in the development and validation of immunoassays (ELISA, RIA) and receptor-binding assays.
• Metabolic Disorder Studies: Investigation of calcium and phosphate homeostasis, bone resorption, and renal function in experimental models.
• Peptide Chemistry & Formulation: Serves as a model compound for studying peptide stability, delivery systems, and analog synthesis.
• Quality Control Laboratories: Employed as a system suitability standard in analytical methods (e.g., HPLC, MS) for related pharmaceutical products.
