title: [Isoelectric heterogeneity of hemoglobin of domestic ducks].
abstract: Electrophoresis in PAAG separates hemoglobin of domesticated ducks into 4 fractions: two major (Hb-1 and Hb-2) and two minor (Hb-3 and Hb-4). All electrophoretic fractions of the mentioned hemoglobin being subjected to isoelectrofocusing within the pH gradient of 6.0:8.0 show a heterogeneity associated with the presence of nine isoelectric components in each fraction. Components with the highest protein content are found to shift towards the acidic region pI in the direction of Hb-1----Hb-2----Hb-3----Hb-4 fractions.
