Objective To determine the composition of abnormal red cell membrane skeletin. Methods By sodium dodecyl sulphate polyacrylamide gel electrophoresis of ghostcorpuscles, we quantified the amount of protein by densitometric *** The results showed that in β-thalassernia, the amount of spectrin, 4.5 protein and globin significantly increased compared with the controls (26.05 + 1.46, 21.69 + 1.86; 22.87 + 5.61, 12.99 +2.33; 15.23+3.31 and 4.97+2.73, respectively, P＜0.05).Conclusion These data suggest that the erythrocyte membrane protein composition matched with globin in patients with β-thalassemia of the racial Li minority are different from the normal control. These factors increase rigidity but decrease deformability of the β-thalassemic red cell membrane, which may lead to hemolytic anemia.
