Abstract
The use of isoelectric focusing in agarose gel was examined to test its usefulness for screening of cord blood Hb and for the identification of Hb variants in general. Advantages of agarose include the following: short running times, ease of preparation and nontoxicity. In cord blood samples identification of Hb S, Hb C and Hb Bart''s was achieved. Separation of 16 Hb variants, including 6 of clinical and geographical importance, was shown.
