Octyl β-D-mannopyranoside (CAS 140147-38-2)

Octyl β-D-mannopyranoside is a non-ionic detergent composed of an octyl chain linked to a mannose sugar via a glycosidic bond. This amphiphilic compound has gained prominence in research for its ability to solubilize and stabilize membrane proteins, which are often challenging to isolate and study due to their hydrophobic domains. The gentle, non-denaturing properties of octyl β-D-mannopyranoside allow researchers to extract these proteins from cellular membranes while maintaining their native conformation and activity. In structural biology, this detergent plays a pivotal role in purifying and crystallizing membrane proteins to determine their 3D structures via X-ray crystallography or cryo-electron microscopy. Its specific affinity for mannose-binding proteins aids in studying lectins and carbohydrate-binding enzymes, helping researchers understand their substrate specificity and enzymatic mechanisms. Additionally, octyl β-D-mannopyranoside is crucial for functional assays involving membrane-bound receptors and transporters. It facilitates the reconstitution of these proteins into artificial lipid bilayers, enabling functional characterization and studying ligand-receptor interactions. Furthermore, this detergent has been used in glycomics research to analyze carbohydrate-protein interactions. By providing a soluble substrate that mimics natural glycan structures, it enables researchers to investigate lectin-binding properties and identify carbohydrate recognition patterns in biological systems. Overall, octyl β-D-mannopyranoside is an invaluable tool in understanding the structure and function of membrane proteins and carbohydrate-binding mechanisms.
