Improved typing of human serum transferrin by isoelectric focusing on ultrathin layer polyacrylamide slab gels.
An improved method for separating transferrin subtypes through the use of isoelectric focusing on ultrathin layer polyacrylamide gels is described. The most considerable problems encountered in the assessment of the Tf phenotypes after pretreatment with iron donor compounds are pointed out. Useful technical devices for reducing the occurrence of artifactitious extrabands are suggested. Finally, the gene frequencies in three samples from Italian populations are reported.
