Abstract

The permeability properties of the resealed ghost membrane depend on the pH at hemolysis. If resealed ghosts are prepared by hypotonic hemolysis at 0°C, pH 6.0 with maximal dilution of endogenous chelators, resealing for Na and K takes place when a new pool of chelators is supplied. However, when prepared by hemolysis at pH 7.6 or above, the cation barrier cannot be restored. A model is suggested where ternary complex formation between an endogenous chelator, Ca and a membrane site control the state of the cation barrier.
