WebResolution by isoelectric focusing in an immobilized pH gradient (pH range 7.35-7.55 over 20 cm path) of two human fetal hemoglobins, one with glycine (lower) instead of alanine (upper) in position 136 of the gamma chains. The isoelectric points of the hemoglobins differ by only 0.003 pH units. Webhemoglobin or can cause a deficiency in the amount of ß-globin being produced. These types of mutations are referred to as ß- ... chromatography (HPLC), isoelectric focusing (IEF) and hemoglobin electrphoresis. Genetic testing to look for mutations in the ß-globin gene can also assist in confirming the diagnosis. Hemoglobinopathies:

Hemoglobin electrophoresis alone is not adequate for diagnosing thalassemia. Electrophoresis is limited to identification without fractionation, quantification or interpretation. WebHemoglobin Assays. Hb electrophoresis (eg, isoelectric focusing [IEF]) or high-performance liquid chromatography (HPLC) may reveal increased HbA2 and HbF. However, unstable Hb variants, particularly hyperunstable variants, undergo rapid denaturation and degradation within the erythrocyte, and remaining Hbs may appear relatively normal.
