Developmental change in microheterogeneity of chicken serum transferrin (Tf) was investigated by polyacrylsmide‐gel isoelectric focusing, direct immunofixation, and densitometry. Three main Tf species (Tf‐0, Tf‐1, and Tf‐2, which have 0, 1, and 2 sialic acid residues per molecule, respectively) were resolved and their relative ratios were determined. As development proceeded, a relative increase occurred in the most acidic species (Tf‐2) with decreases in the less acidic ones (Tf‐0 and Tf‐1).
