Mapping of several abnormal hemoglobins by horizontal polyacrylamide gel isoelectric focusing.

The relative mobilities of serveral human hemoglobin variants were studied by use of an isoelectric focusing method in a thin-layer horizontal polyacrylamide gel. The technic is described in detail and a preliminary mapping of these variants is presented. It appears that thin-layer gel isoelectric focusing is a method that is rapid, highly reproducible and easily applicable in laboratories concerned with the study of hemoglobinopathies.
