The effects of valinomycin (25 pM) on the membrane potential and on initial, passive Na+ and K + movements have been determined in Ehrlich ascites tumor cells. The membrane potential of steady-state cells in a physiologic environment was -23.2 mV. Addition of valinomycin induced a small, significant

The effect of di-and trivalent cations on the membrane potential of the Ehrlich ascites tumor cell has been investigated using micro-electrode techniques. In solutions free of multivalent cations the average membrane potential for 46 cells was 8.3 f 0.5 mv (SE). However, the potentials were not stab
The electrical potential difference (PD) across the membrane of the Ehrlich mouse ascites tumor cell has been measured with iniracellular microelectrodes. The mean for 111 cells in control Ringer solution was -11.2 m V ? 0.29 (SE), interior negative. When sulfate replaced chloride in the external me
## Abstract The effect of Ca^+2^ on the transport and intracellular distribution of Na^+^ and K^+^ in Ehrlich ascites tumor cells was investigated in an effort to establish the mechanism of Ca^+2^βinduced hyperpolarization of the cell membrane. Inclusion of Ca^+2^ (2mM) in the incubation medium lea
## Abstract We have investigated the effects of the amino reactive reagent, 2,4,6βtrinitrobenzene sulfonic acid (TNBS) on anion transport (chloride and sulfate) and on the K^+^ content of Ehrlich ascites tumor cells. Incubation of tumor cells with TNBS (3 mM or 10 mM) results in a time dependent up
