Description

Mesotocin is a nonapeptide hormone and neuropeptide, structurally related to oxytocin and vasopressin. This compound is of significant interest in biochemical and pharmacological research for studying the evolution and function of neurohypophysial hormone systems across different species. It serves as a critical tool for researchers and developers in the fields of comparative endocrinology, neuroscience, and veterinary pharmaceuticals, particularly for investigations into reproductive and social behaviors in non-mammalian vertebrates.

Application

• Neuroscience Research: Used as a reference standard and active agent in studies of neuropeptide receptors, neural pathways, and social behavior mechanisms.
• Comparative Endocrinology: Essential for research on the evolution, structure-activity relationships, and physiological roles of oxytocin-family hormones in birds, reptiles, and amphibians.
• Veterinary Pharmaceutical Development: Investigated for potential applications in managing reproductive functions and stress responses in avian and reptilian species.
• Biochemical Assays: Serves as a high-purity standard in immunoassays (ELISA, RIA) and receptor binding studies to ensure accurate quantification and analysis.
• Academic & Institutional Research: A key reagent for university and government labs conducting fundamental research in animal physiology and behavior.
