Description_x000D_ General description_x000D_ Nonyl β-D-glucopyranoside is a nonionic surfactant among a small number of surfactants found to be useful for the solubilization and crystallization of a large number of biological membrane proteins._x000D_ Application_x000D_ Nonyl β-D-glucopyranoside has been used in a study to assess the structure and molecular fluctuations of n-alkyl-β-d-glucopyranoside micelles. It has also been used in a study to investigate enantiomer separation of drugs by micellar electrokinetic chromatography.
