A possible Na/Ca exchange in the follicle cells of Xenopus oocyte

In manually dissected Xenopus oocytes, we found that the replacement of external sodium by Tris, choline, or lithium induced a large membrane depolarization and, in voltage clamp, a large inward current. This current appears to be due to activation of a calcium-dependent chloride conductance since i...
