title: Separation of transferrin types in human plasma by anion-exchange high-performance liquid chromatography.
abstract: An anion-exchange high-performance liquid chromatographic procedure was developed for the separation of transferrin in human plasma. The procedure allowed the four molecular forms of transferrin, which differ with respect to bound iron, to be separated from each other and from other plasma proteins. Transferrin variants, including B and D types, could also be identified using anion-exchange high-performance liquid chromatography. The approach followed for optimizing the separation of transferrin included identification of the peaks in the chromatogram by two-dimensional polyacrylamide gel electrophoresis. This approach could be extended to other proteins in plasma or biological fluids in order to optimize their separation.
