The movement of sulfobromophthalein is measured in rat liver plasma-membrane vesicles by direct dual-wavelength spectrophotometry. The technique is based on the principle that the dye, when entering a more acidic compartment, changes its absorption in the visible region. From this study it may be concluded that, among the different cellular subfractions, only liver plasma-membrane vesicles can catalyze electrogenic transport of sulfobromophthalein. Plasma membranes from erythrocytes are unable… CONTINUE READING
