title: Iron-binding activity of female-specific serum proteins of rainbow trout (Salmo gairdneri) and chum salmon (Oncorhyncus keta).
abstract: The differences of serum proteins between mature male and female rainbow trout (Salmo gairdneri) and chum salmon (Oncorhyncus keta) were studied electrophoretically and immunologically. Female-specific serum proteins were seen only in females of both species, in the same region as beta-globulin on cellulose acetate membrane electrophoresis and agarose gel immunoelectrophoresis. One of the female-specific serum proteins bound radioactive iron. This protein was partially purified by precipitation by lowering the ionic strength of the serum. The purified material also showed the iron-binding property.
