[Concentration of black spots and the effect of detergents on black lipid membranes].

Effect of water-soluble detergents, such as triton X-100, saponin and trimethyl octadecylammonium bromide on the concentration of black spots, tension and stability of black lipid membranes was studied. Changes in mechanic stability of the lipid bilayer are discovered, which are in a good correlation with the litic effect of true detergents on cell membranes.
