Hp from sla retains a reduced ferroxidase activity. (A) Mouse enterocyte protein extract ([A] 200 μg or [B] 80 μg) was prepared from a normal mouse (C57/BL/6J) or an sla mouse was resolved by nondenaturing, nonreducing gel electrophoresis. Gels were incubated with ferrous ammonium sulfate, developed with ferrozine, and photographed as color developed. Purified human ceruloplasmin (Cp) was used as a control. The upper and lower arrows indicate the mobilities of Hp and Cp, respectively.
