Description and Uses

Methyl-β-cyclodextrin is a randomly methylated form of the cyclic oligosaccharide β-cyclodextrin . Methyl-β-cyclodextrin contains seven D-(+)-glucopyranose units that contain randomized hydrogen or methyl groups. Methyl-β-cyclodextrin has been used to improve the aqueous solubility of various compounds and to extract cholesterol from lipid membranes. Methyl-β-cyclodextrin (5 mM) reduces α-synuclein levels in the membrane and detergent-insoluble fractions from B103 neuroblastoma cells transfected with human α-synuclein. It also reduces α-synuclein levels in mouse brain in a transgenic model of α-synucleinopathy.

Methyl-β-cyclodextrin is a cholesterol-removing agent mainly used for lipid raft disruption. It may also be used for detergent removal from protein-lipid-detergent ternary mixture to produce 2D membrane protein crystals due to its high solubility and affinity for detergents generally used in membrane protein chemistry.
