Separation of dense cells and their morphology. (A) RBCs were separated with an arabinogalactan density discontinuous gradient into 7 bands (H1 to H7) using blood from Prx II^–/– mice (left) and 6 bands (W2 to W7) using blood from wild-type mice (right). (B) Abnormally shaped RBCs were found in all fractions (H1 to H7) from the Prx II^–/– mice. Spherocytes (Sp), schistocytes (Sc), burr cells (B), and polychromatophilic macrocytes (P) are indicated.
