Description

Peptide YY, Human is a 36-amino acid peptide hormone that plays a critical role in regulating appetite and energy homeostasis. This high-purity compound is essential for advanced research in endocrinology and metabolic disorders. It is primarily utilized by pharmaceutical R&D teams, academic research institutions, and diagnostic manufacturers for applications in drug discovery, biochemical assays, and metabolic studies.

Application

• Pharmaceutical Research & Development: Used as a reference standard and active ingredient in the development of novel therapeutics for obesity, diabetes, and related metabolic syndromes.
• Biochemical & Physiological Studies: Employed in in vitro and in vivo research to investigate the mechanisms of appetite regulation, gut-brain axis signaling, and pancreatic function.
• Diagnostic Kit Manufacturing: Serves as a critical component (antigen/calibrator) in the production of immunoassay kits for the quantitative measurement of PYY levels in biological samples.
• Academic & Clinical Research: A key tool for universities and hospitals studying gastrointestinal hormones, satiety signals, and their role in health and disease states.
• Cell Culture & Receptor Binding Assays: Used to stimulate or inhibit specific pathways in cell-based models to study Y receptor (Y1, Y2, Y5) activation and downstream effects.
