Description

Ac-δ-Endorphin (Human) is a synthetic peptide fragment corresponding to the N-acetylated form of the endogenous human δ-endorphin sequence. This high-purity biochemical is critical for research applications requiring precise molecular tools to study opioid receptor interactions and neuropeptide signaling pathways. It is primarily utilized by pharmaceutical R&D teams, academic neuroscience laboratories, and biotechnology companies focused on central nervous system drug discovery and peptide-based therapeutic development.

Application

• Neuroscience Research: Used as a reference standard and active agent in studies of opioid receptor binding, selectivity, and signal transduction mechanisms.
• Biochemical Assay Development: Serves as a critical component in the development and validation of competitive binding assays (e.g., ELISA, RIA) for endorphin detection.
• Pharmacological Profiling: Employed in vitro and in vivo to investigate the physiological effects, potency, and metabolic stability of δ-endorphin analogs.
• Drug Discovery Screening: Acts as a lead compound or template for the design and synthesis of novel peptide-based analgesics and neuro-modulators.
• Academic & Clinical Studies: Supports fundamental research into pain perception, stress response, and addictive behaviors related to the endogenous opioid system.

Quality Control

Every batch of Ac-δ-Endorphin (Human) is manufactured under strict quality management systems and undergoes comprehensive analytical testing. We ensure compliance with high-purity standards suitable for research and development. A detailed Certificate of Analysis (COA) providing purity, identity, and impurity profiles via HPLC, MS, and amino acid analysis is provided with each shipment to guarantee traceability and product integrity.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dry environment. 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 absorption.
