Transferrin Subtyping in Human Organ Tissues

Serum transferrin (TF) exhibits genetic polymorphism with 2 codominant alleles, TF*C1 and TF*C2 (Kilian’ and Spielmann 1978, Thymann 1978). By means of sensitive immunoblotting techniques, the TF subtypes have been demonstrated also in bloodstains (Yamaha et al. 1991), semen (Yamaba et al. 1991), urine (Kishi et al. 1990) and dental pulps (Kido et al. 1993). In this study we report the results of TF subtyping in human organ tissues using immunoblotting after isoelectric focusing.
