Summary The experiments presented below compared the interaction of diO-C3-(5) and diS-C3-(5) with erythrocytes, erythrocyte ghosts and phospholipid vesicles derived from erythrocyte membranes. The results confirm earlier reports of diS-C3-(5) dimerization in the presence of hemoglobin and of dye aggregate formation in erythrocyte suspensions. DiO-C3-(5), on the other hand, binds to vesicles and ghosts freed of hemoglobin in a potential-dependent manner but without forming dye aggregates. The two dyes bind to the different preparations in similar proportions, but diS-C3-(5) is bound in amounts 3–40 times greater depending on the degree of polarization.
