Description

β-Endorphin (2-9) is a specific bioactive peptide fragment derived from the endogenous opioid peptide β-endorphin. This compound is a critical research tool for studying opioid receptor interactions, neurobiology, and pain modulation pathways. It is primarily utilized by pharmaceutical R&D teams, academic researchers, and biochemical suppliers focused on neuroscience, analgesic development, and peptide chemistry.

Application

• Neuroscience Research: Used as a reference standard and active agent in studies of opioid receptor binding, signal transduction, and neuropeptide function.
• Analgesic Drug Discovery: Serves as a key intermediate or pharmacological probe in the development of novel pain management therapeutics.
• Biochemical Assays: Employed in competitive binding assays (e.g., ELISA, RIA) and in vitro functional studies to characterize receptor affinity and efficacy.
• Academic & Pharmaceutical R&D: Essential for fundamental research into endorphin metabolism, structure-activity relationships (SAR), and peptide hormone processing.
• Reference Standard: Provides a high-purity standard for the quality control and identification of related peptide materials.
