Digitonin is a kind of spirostan saponin obtained from the seeds and the leaves of Digitalis purpurea.D.lanata. It is mild nonionic detergent and used to solubilize membrane proteins. It also can be used to solubilize the neurotransmitter receptors such as dopamine receptor, beta adrenergic receptor, GABA receptor.
Although Digitonin is usually insoluble in water, we provide water-soluble Digitonin for Biochemistry (>4% solubility), which was made possible by our original purification method.
