Bar histogram of surface expression of murine GPA and band 3.

(A) Wild-type (░) and GYPA transgenic (■) mouse red blood cells were labeled with varying concentrations of TER-119–PE and analyzed by flow cytometry. (Wild type: n = 4; transgenic: n = 3.) (B) Band 3 in wild-type and GYPA transgenic mouse red blood cells was labeled with varying concentrations of EMA and analyzed by flow cytometry. (Wild type: n = 4; transgenic: n = 3.) The error bars represent SDs.
