Abstract
In accordance with the invention the glycosylated hemoglobin in a blood sample is electrophoretically separated from the other constituents by including dextran sulphate in the electrophoresis buffer, or by mixing a solution of the dextran sulphate with the blood sample prior to the electrophoresis, such that the blood is in contact with dextran sulphate during the electrophoresis. The presence of the dextran sulphate results in a clear and well defined electrophoretic separation of the glycosylated hemoglobin from the non-glycosylated hemoglobin, thereby enabling accurate glycosylated hemoglobin determination.
