Osmotic properties of bovine erythrocytes aged in vivo.
The osmotic properties of bovine erythrocytes aged in vivo were studied by the modified microhematocrit method. The osmotic fragility of older red cells decreases due to their larger relative osmotically non-active volume. Relative critical cell volume of bovine erythrocytes does not alter significantly with cell age. The age dependent change in the osmotic fragility of human red blood cells, the reverse of that found for bovine erythrocytes, is due to a different alteration of the critical cell volume during intravascular erythrocyte aging.
