Steroid glycoside and non-ionic detergent with high binding capacity for cholesterol. Digitonin is used for permeabilisation of plasma membranes as well as for mild solubilisation of membrane-bound proteins.
Application: Use 10 -100 µg/ml for selective permeabilisation of plasma membranes via binding of cholesterol (Mooney, R.A. (1988). Methods Enzymol. 159:193-2).
