Description

δ-Endorphin CAS NO 69599-55-9 is a specific endogenous opioid peptide, a fragment of the pro-opiomelanocortin (POMC) precursor, known for its potent analgesic and neuroregulatory activities. This high-purity peptide is critical for advanced research in neurobiology, pain management, and the development of novel therapeutic agents. It is an essential biochemical tool for pharmaceutical R&D laboratories, academic research institutions, and biotechnology companies focused on central nervous system disorders and opioid receptor pathways.

Application

• Neuroscientific Research: Fundamental studies on endogenous opioid systems, receptor binding assays, and signal transduction pathways.
• Analgesia & Pain Management R&D: Investigation of natural pain-relief mechanisms and development of next-generation, non-addictive analgesic drugs.
• Behavioral & Psychiatric Studies: Research into the role of endorphins in stress response, mood regulation, and reward mechanisms.
• Biochemical Standard & Reference Material: Use as a certified reference standard in analytical methods like HPLC and mass spectrometry for quality control and assay validation.
• Drug Discovery Platforms: High-throughput screening (HTS) for identifying and characterizing compounds that modulate opioid receptor activity.
• Academic & Clinical Research: Supporting university-led projects and clinical investigations into the physiological and pathological roles of opioid peptides.

Quality Control

Our δ-Endorphin is manufactured under stringent conditions to ensure the highest standards of purity and batch-to-batch consistency, suitable for sensitive research applications. Each lot undergoes comprehensive analytical characterization, including HPLC for purity, MS for identity confirmation, and amino acid analysis. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all critical quality attributes. We adhere to a quality management system designed to meet the rigorous demands of the pharmaceutical and life science research sectors.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dedicated freezer. This product is hygroscopic (moisture-sensitive). For long-term storage, consider desiccant and under an inert atmosphere. Allow the vial to equilibrate to room temperature before opening to minimize moisture condensation.
