Immunoblotting analysis of CHC and SAO RBC membranes, as compared to cRBC or standard RBC membranes, showed a similar protein profile to the sdCHC RBC membranes, except for the TfR in the SAO cells, and CD147 in CHC cells, suggesting that CHC and SAO RBCs also present incomplete maturation when compared to standard RBCs, but mature to a greater extent than OHSt cells [120]. Here, BSG is linked to southeast Asian ovalocytosis.
