1. Changes in the fluorescent intensity of the dye, 3,3'-dihexyl-2,2'-oxacarbocyanine, added to suspensions of human and Amphiuma red blood cells were measured in parallel with changes in the membrane potentials of these cells. In these studies the membrane potential was altered in three different ways: by the addition of valinomycin to alter the ratio, P(K)/P(Cl), by a change in the pH of the medium to alter the ratio, Cl(c)/Cl(0), and by the substitution of impermeant anions for Cl(0) again… CONTINUE READING
