Description

Peptide Yy CAS NO 106388-42-5 is a 36-amino acid peptide hormone that plays a critical role in regulating appetite and energy homeostasis. Its primary value lies in its potent anorexigenic effects, making it a key compound for metabolic research and therapeutic development. This product is essential for researchers and manufacturers in the pharmaceutical, biotechnology, and life science sectors focused on endocrinology, obesity, and diabetes.

Application

• Pharmaceutical Research & Development: As a reference standard and active ingredient in preclinical studies for anti-obesity and anti-diabetic drug candidates.
• Metabolic Disorder Studies: Used in in vitro and in vivo models to investigate the Y receptor signaling pathways and their role in satiety and glucose metabolism.
• Biochemical Assay Development: Serves as a critical component in the development and validation of immunoassays (e.g., ELISA, RIA) for quantifying PYY levels in biological samples.
• Academic & Clinical Research: Fundamental tool for universities and hospitals studying gastrointestinal endocrinology, bariatric surgery outcomes, and gut-brain axis communication.
• Peptide Chemistry & Synthesis: Used as a benchmark for synthetic peptide quality and for studying structure-activity relationships (SAR) of neuropeptide Y family hormones.
