Haemoglobin and the red cell membrane.
The results presented here indicate that haemoglobin is an integral part of the red cell membrane. The haemoglobin content of the membrane is highly dependent on the Ca++ content of the membrane in health and disease. Changes in the red cell interior alter the whole organization of the membrane and are even reflected in the binding of immunoglobulins to the red cell surface. The preferential binding of Hb-s A2 and S to the membrane has been confirmed. This phenomenon cannot be explained by differences in the charge between these haemoglobins and Hb A.
