[Latent iron-binding capacity of normal serum proteins by means of Fe-59].

Experimental investigations were carried out for confirming the possibility of saturation of the basic serum components with exogenous iron (not only transferin). In gel chromatography, paper electrophoresis and acetate cellulose electrophoresis it was demonstrated that the latent capacity for iron saturation is a feature of not only transferrin belonging to beta1 globulins, but also to some extent of albumins and alpha-globulins. Iron distribution was studied after 59Fe administration. The iron-binding capacity of alpha-globulins was many times higher than that of albumins.
