The binding sites for opiates (agonist and antagonist) and opioid peptides can be solubilized from rat brain membranes with digitonin in the presence of Mg2+ (10 mM). High affinity and high capacity binding to the soluble delta, mu, and kappa

A major methodological problem in the intracellular localization of cholesterol is the nearly complete extraction of sterols during routine dehydration and embedding procedures for electron microscopy. Cholesterol digitonide (a sterol complex with digitonin), however, is qualitatively insoluble in these solvents.
