Membrane proteins in hereditary spherocytosis, elliptocytosis and stomatocytosis

Cell membrane proteins of patients with hereditary spherocytosis, elliptocytosis and stomatocytosis were analyzed by SDS acrylamide gel electrophoresis. From 7 patients with hereditary spherocytosis only one can be supposed to have a reduction of a band with a molecular weight of about 80,000 daltons. 3 members of a family with hereditary elliptocytosis and 1 patient with hereditary stomatocytosis did not differ from the donors. The question of the nature of membrane defect in haemolytic anaemias could not be answered by the results obtained.
