The location of structural difference between ovotransferrin types A and B in hens.
A comparison of ovotransferrin types A and B showed that in starch gel electrophoresis both types consisted of one major and one minor component. Both types have a similar amino acid composition as do the fragments from each type. Starch gel electrophoresis shows that the cause of the difference in the electrophoretic mobilities between ovotransferrin types A and B lies in the C-terminal half of the molecule. No physiological difference was found between types A and B, both types donate iron to chicken embryo red cells at equal rate.
