Figure 5.

Figure showing the change in current 900 s after exposure to SDS, CTAB, and ORB dissolved in ECS. SDS and ORB induce increased membrane permeability at 0.2 mM, respectively, while CTAB and ORB induce membrane permeability at 0.01 and 0.014 mM, respectively. CTAB induces permeability at concentrations 20 times less than SDS and 14 times less than ORB. The relative activity of SDS:CTAB:ORB is thus 1:20:14 as measured by this method.
