Non-Ionic, Biocompatible Detergent for Membrane Protein Solubilization and Structural Biology Applications
Thermo Scientific™ Octyl-β-D-glucoside (OG) is a high-purity, non-ionic detergent widely used in biochemical, biophysical, and structural biology research for the solubilization and stabilization of membrane proteins. Derived from glucose and containing an octyl alkyl chain, OG is particularly valued for its mild, non-denaturing properties, allowing researchers to maintain the native conformation and functionality of proteins during extraction, purification, and crystallization workflows.
Its low UV absorbance and defined micelle-forming properties make OG highly suitable for spectroscopic, chromatographic, and crystallographic applications.
Key Features & Benefits
- Non-Ionic & Gentle – Minimizes protein denaturation; suitable for delicate membrane proteins
- High Aqueous Solubility – Forms clear and stable solutions, even at high concentrations
- Defined Micelle Behavior – Facilitates consistent protein solubilization with predictable behavior
- Low UV Absorbance – Ideal for absorbance-based detection or spectroscopic analysis
- High Purity for Research Use – ≥99% purity, suitable for sensitive and high-resolution workflows
Applications
- Membrane Protein Extraction – Solubilizes integral membrane proteins for biochemical and structural analysis
- Protein Crystallization – Commonly used in X-ray crystallography and NMR sample preparation
- Structural Biology – Suitable for cryo-EM, SAXS, and other protein conformation studies
- Liposome & Micelle Studies – Model membrane systems, protein-lipid interaction analysis
- Protein Refolding – Supports reconstitution of functional proteins from denatured states
