A comparison of two procedures useful for the isolation of Hb F from adult red blood cells and for the quantitation of the types of gamma chain by high-performance liquid chromatography.
Two methods have been used to isolate Hb F from red cells with low levels of Hb F (less than 2% FAD), namely an alkali denaturation procedure, as described by Tsuchiya et al. [Dokkyo J. Med. Sci., 10 (1983) 13], and anion-exchange chromatography. Analyses of these Hb F enriched hemoglobin solutions by high-performance liquid chromatography allowed quantitation of the different gamma chains in the Hb F. Although the data showed considerable variation, particularly for samples with low levels of Hb F, the final results obtained with the two approaches were comparable, suggesting that the much simpler and more economical alkali denaturation procedure can be used for this purpose.
