This electrophoresis gel displays the migration patterns for a person with normal hemoglobin distribution. Normally Hb A is present in excess of 95% with the remaining being made up of Hb A2 and Hb F.
Here you can see the large band of Hb A with a faint band in the Hb F and Hb A2 regions.
Controls for A and F and A, S, and C are included.
(AF and ASC are simply labels for the controls and do not indicate order of migration.)
