Method "The permeability coefficient, P (cm/sec), of the red cell membrane was calculated by: P= kV[w]/A, (equation 2) where V[w]/A is the ratio (in cm) of the cell water volume to the cell membrane area that changes during maturation (-k is equal to the rate coefficient for the unidirectional tracer efflux.)"
Comments "On each day one batch of cells was used for one or two control experiments, as described in the Methods section. The cells were next recovered, reloaded with radioactive chloride and bicarbonate (cf. Methods section) and used for another efflux experiment. The re-use procedure and flux experiment were repeated two or three times."
