Hemoglobin separation

WebFetal hemoglobin (HbF) has two α- and two γ-globin chains (α 2 γ 2 ). Minor adult hemoglobin (HbA 2) is made of two α- and two δ-globin chains (α 2 δ 2 ). Hemoglobin electrophoresis has been superseded by more rapid, sensitive, and quantitative methods of hemoglobin separation. What are the types of hemoglobin (Hb)? Webored molecules hemoglobin and vitamin B12 to illustrate the principles of SEC. Hemoglobin (reddish-brown) is much larger than vitamin B12 (pink), and thus passes through the column more quickly than vitamin B12. The students can easily visualize the separation of these molecules as they pass through the column and into collection tubes. 4
