Description
Digitonin is a mild detergent that permeabilizes plasma membranes completely and selectively due to their high cholesterol content, whereas mt-membranes with lower cholesterol content are affected only at higher concentrations. Optimum digitonin concentrations for complete plasma membrane permeabilization of cultured cells can be determined directly in a respirometric protocol.
