Separation of normal and abnormal hemoglobin chains by reversed-phase high-performance liquid chromatography.
A review is presented of the elution patterns on reversed-phase columns of the normal and abnormal globin chains of different hemoglobin types, including 16 beta-chain variants, 7 alpha-chain variants, 9 gamma-chain variants, and 4 variants with fusion or hybrid chains. Separations appear to be based primarily on differences in hydrophobicity. The method is ideally suited for the detection of abnormal globin chains, their quantitation and their isolation. Semi-quantitative data based on the calculation of the delta/non-alpha ratios allow the detection of beta-thalassemic conditions in situations where the quantitation of hemoglobin A2 by other procedures is impossible or complicated.
