Expression of Hp and Hx in the plasma of Hx-null and Hp-null mice, respectively.

(A) Hp expression. (i) A representative Western blot of plasma proteins of a wild-type, an Hx^−/−, and an Hp^−/− mouse assayed for Hp expression under basal conditions and after φhyd injection. (ii) Densitometric analyses of separate Western blots. Three mice of each genotype were analyzed at each time point. (B) Hx expression. (i) A representative Western blot of plasma proteins of a wild-type, an Hp^−/−, and an Hx^−/− mouse assayed for Hx expression under basal conditions and after φhyd injection. (ii) Densitometric analyses of separate Western blots. Three mice of each genotype were analyzed at each time point. *P < .02, **P < .01, ***P < .001.
