Fig. 8. Chelating extracellular Ca2+ inhibited whole-cell currents in
swollen erythrocytes. Cells were maintained at a holding potential of -15 mV
and stepped to potentials between -100 to +100 mV in 20 mV intervals. (A)
Whole-cell currents for an erythrocyte exposed to a hypotonic (0.5x) KCl
Ringer solution and inhibition of these currents by adding EGTA (5 mM) to the
bath. (B) Corresponding current-voltage (I-V) relationship for control
(hypotonic Ringer) and low Ca2+ solutions (n=5). Values
are means±s.e.m.
