Hemoglobin electrophoresis in alkaline (A) and acid gel (B), and by isoelectric focusing (C and D). Hb M Iwate is anodal to Hb A in alkaline gel and undistinguishable from Hb A in acid gel. Its color is brown in contrast to the vivid red of Hb A before trichloroacetic acid is applied to the isoelectric focusing gel (C). It runs between Hb F and Hb S (closer to Hb F) after the gel has been fixed and dried (D).
