Six phenotypes TfC1, TfC2, TfC1C2, TfC1C3, TfC1Dchi and TfC2Dchi were detected by isoelectric focusing with immobilized pH gradients in pH 5.05～5.60. Tf^C3 has never been revealed in the Han population before. The Gene frequencies are as follows: Tf^C1=0.7420, Tf^C2=0.2420, Tf^C3=0.0027, Tf^Dchi=0.0133. There is a good agreement between the observed and expected values corresponding to the Hardy-Weinberg equilibrium. The allele frequencies for Tf^C1, Tf^C2 and Tf^Dchi are quite similar to those previously reported.
