Digitonin is a mild nonionic detergent. It permeabilizes plasma membranes of eukaryotic cells by complexing with membrane cholesterol and other unconjugated β-hydroxysterols.


  • Water soluble
  • Critical Micelle Concentration (CMC): <0.5 mM (20…25 °C)(Lit.)
  • [α]20/D −54 °, c = 2.8 in methanol (Lit.)


Digitonin has used for cholesterol determination, use of digitonin-permeabilised adipocytes for cAMP studies, solubilisation of membrane proteins. The water soluble form can be used for the isolation of mitotic chromosomes. Mild nonionic detergent used to solubilise receptors and permeabilise cellular and nuclear membranes.
