title: Permeability increase in black lipid membrane induced by compound 48/80.
abstract: When compound 48/80, a potent histamine liberator, was added in the aqueous phase facing the black lipid membrane, the conductivity of the membrane was remarkably increased. Although valinomycin displayed a distinct selectivity for K+ movement, such selection for ionic permeability was not observed in the case of compound 48/80.
