an exact biochemical characterization of some different types of hereditary spherocytosis , hereditary elliptocytosis , hereditary pyropoikilocytosis and the hemolytic anemias with increased cation permeability ( hereditary stomatocytosis ) is possible after analysis of membrane proteins with sds-polyacrylamide gel electrophoresis , quantitative determination of spectrin , the relation of dimeric to tetrameric spectrin , and partial tryptic digestion of the spectrins .
