Transferrin polymorphism detected in human urine using isoelectric focusing followed by immunoblotting.
Genetic polymorphism of transferrin (TF) was revealed in human urine by isoelectric focusing and immunoblotting on thin-layer polyacrylamide gels. Using this technique more than 300 urine samples were examined, and correct TF typing from a small volume of urine (approx. 0.5 ml) was achieved, in comparison with the results of direct grouping for plasma. Three common phenotypes, TF C1, C2-1 and C2, were differentiated. In addition, the rare types TF C1D, C2D, and C1B were observed. The frequencies of the TF alleles in our samples were found to be: TF*C1 = 0.7265, TF*C2 = 0.2624, TF*D = 0.0083 and TF*B = 0.0028.
