Pregnancy and guinea-pig isotransferrins--isolation and characterization of both isotransferrins.
Microheterogeneity patterns of pregnant and non-pregnant guinea-pig serum transferrin differ significantly. Using preparative isoelectric-focusing 'slow' and 'fast' isotransferrins were separated. Amino-acid and carbohydrate composition of these two fractions are presented.
